Answer:
format floating-point numbers in fixed-point notation
Explanation:
Required
Function of fixed manipulator
This question will be answered from the perspective of C++ programming language (however, the explanation is applicable to programming languages that uses fixed manipulators)
Fixed manipulators in C++ is used to set floating point numbers to a stated fixed point.
Take for instance;
double pi = 3.1415926534;
cout.precision(2);
cout<< fixed << pi;
The third line of the program where the fixed manipulator is used to format pi to 2 fixed point notation.
Hence, the output will be 3.14
Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which a and b are integers and b is not equal to 0. Your program must be menu driven, allowing the user to select the operation ( , -, *, or /) and input the numerator and the denominator of each fraction. Furthermore, your program must consist of at least the following function
menu: This function informs the user about the program's purpose, explains how to enter data, how to quit and allows the user to select the operation.
addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result.
subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the numerator and denominator of the result.
multiplyFractions: This function takes as input four integers representing the numerators and denominators of two fractions, multiplies the fractions, and returns the numerator and denominator of the result.
divideFractions: This function takes as input four integers representing the numerators and denominators of two fractions, divides the fractions, and returns the numerator and denominator of the result.
Here are some sample outputs of the program:
3 / 4 +2 / 5 = 23 / 20
2 / 3 * 3 / 5 = 2 / 5
Answer:
Explanation:
The following code is written in Java, It asks the user to enter the numerator and denominator for both fraction 1 and 2. Then it prompts the user with a menu to choose the desired operation. The choice is passed into a switch statement and calls the correct function.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int num1, num2, den1, den2;
System.out.println("Enter numerator for fraction 1: ");
num1 = in.nextInt();
System.out.println("Enter denominator for fraction 1: ");
den1 = in.nextInt();
System.out.println("Enter numerator for fraction 2: ");
num2 = in.nextInt();
System.out.println("Enter denominator for fraction 2: ");
den2 = in.nextInt();
System.out.println("Menu:");
System.out.println("+ = add fractions");
System.out.println("- = subtract fractions");
System.out.println("/ = divide fractions");
System.out.println("* = multiply fractions");
String answer = in.next();
switch (answer.charAt(0)) {
case '+': add(num1, den1, num2, den2); break;
case '-': subtract(num1, den1, num2, den2); break;
case '*': multiply(num1, den1, num2, den2); break;
case '/': divide(num1, den1, num2, den2); break;
}
}
public static void add(int num1, int den1, int num2, int den2) {
int num3 = (num1 * den2) + (num2 * den1);
int den3 = den1 * den2;
System.out.println("New Fraction: " + num3 + " / " + den3);
}
public static void subtract(int num1, int den1, int num2, int den2) {
int num3 = (num1 * den2) - (num2 * den1);
int den3 = den1 * den2;
System.out.println("New Fraction: " + num3 + " / " + den3);
}
public static void divide(int num1, int den1, int num2, int den2) {
int num3 = num1 * den2;
int den3 = den1 * num2;
System.out.println("New Fraction: " + num3 + " / " + den3);
}
public static void multiply(int num1, int den1, int num2, int den2) {
int num3 = num1 * num2;
int den3 = den1 * den2;
System.out.println("New Fraction: " + num3 + " / " + den3);
}
}
Which XXX completes the definition of the generic method, avgNum?
public class FindAverage { XXX { long tripleSum; tripleSum = item1.longValue() + item2.longValue() + item3.longValue(); return tripleSum / 3; } }
a. public static long avgNum(long item1, long item2, long item3)
b. public static long avgNum(TheType item1, TheType item2, TheType item3)
c. public static long avgNum(TheType item1, TheType item2, TheType item3)
d. public static avgNum(TheType item1, TheType item2, TheType item3)
Answer:
Explanation:
The correct piece of code for the generic method in the question would be the following...
public static <TheType extends Number> long avgNum(TheType item1, TheType item2, TheType item3)
This declaration of the avgNum method declares this method as a Generic TheType method that is a subclass of the Number class. It also takes in generic parameters which are the same as the Generic class that was declared. Finally, outputting a long value which would be tripleSum / 3

A decimal number is called a float.
True
False
Answer: True
Explanation:
The term floating point is derived from the fact that there is no fixed number of digits before and after the decimal point; that is, the decimal point can float. There are also representations in which the number of digits before and after the decimal point is set, called fixed-pointrepresentations.
Answer:
It's true
Explanation:
Your company has a benchmark that is considered representative of your typical applications. One of the older-model workstations does not have a floating-point unit and must emulate each floating-point instruction by a sequence of integer instructions. This older-model workstation is rated at 120 MIPS on this benchmark. A 3rd -party vendor offers an attached processor that is intended to give a hardware accelerator to your workstation. The attached processor executes each floating-point instruction on a dedicated processor, without emulation. The workstation/attached processor rates 80 MIPS on the same benchmark. The following symbols are used to answer this exercise:
I – Number of integer instructions executed on the benchmark
F – Number of floating-point instructions executed on the benchmark
Y – Number of integer instructions to emulate a float-point instruction
W – Time to execute the benchmark on the processor alone
B – Time to execute the benchmark on the processor/coprocessor combination.
Required:
a. Write an equation for the MIPS rating of each configuration using the symbols above.
b. What is the value of B?
c. What is the MFLOPS rating of the system with the coprocessor?
d. Your colleague wants to purchase the coprocessor even though the MIPS rating for the configuration using the coprocessor is less than that of the processor alone. Is your colleague’s evaluation correct?
Answer:
a-The equation for processor only configuration is [tex]120\times 10^6=\dfrac{I+YF}{W}\\[/tex] while that for processor and co-processor configuration is [tex]80\times10^6=\dfrac{I+F}{B}[/tex].
b-The value of B is 1.1 second.
c-The value of MFLOPS for co-processor system in configuration 2 is 80 MFLOPS.
d-The evaluation of your colleague is correct.
Explanation:
a
The MIPS rating equations are as follows
Configuration 01 (Processor only)
[tex]120\times 10^6=\dfrac{I+YF}{W}\\[/tex]
Configuration 02 (Processor + Co-processor)
[tex]80\times10^6=\dfrac{I+F}{B}[/tex]
b
From the equation, for processor and co-processor equation the value of B is calculated. For it to be calculated, the I value is calculated from the processor configuration with the following data F= 8 * 10^6 . Y= 50, W = 4 sec:
[tex]I=120\times10^6\timesW-YF\\I=(120\times10^6\times4)-(8\times10^6\times50)\\I=80\times10^6 \text{instructions}[/tex]
Using this value of I gives
[tex]B=\dfrac{I+F}{80\times10^6}\\B=\dfrac{80\times10^6+8\times10^6}{80\times10^6}\\B=\dfrac{88\times10^6}{80\times10^6}\\B=1.1\text{second}[/tex]
The value of B is 1.1 second.
c
The MFLOPS rating of configuration 2 is given as
[tex]\text{MFLOPS}=\dfrac{F}{B-\dfrac{I}{MIPS_{proc+coproc}}}\\\text{MFLOPS}=\dfrac{8\times10^6}{1.1-\dfrac{80\times10^6}{80\times10^6}}\\\text{MFLOPS}=\dfrac{8\times10^6}{1.1-1}\\\text{MFLOPS}=\dfrac{8\times10^6}{0.1}\\\text{Processor+Coprocessor MFLOPS}=80 \text{MFLOPS}[/tex]
So the value of MFLOPS for co-processor system in configuration 2 is 80 MFLOPS.
d
The value of W is 4 seconds while the value of B is 1.1 seconds. Despite being the configuration with lower MIPS, the co-processor configuration has a lower execution rate and thus the evaluation of your colleague is correct.
Write a MIPS assembly language program that prompts for a user to enter a series of floating point numbers and calls read_float to read in numbers and store them in an array only if the same number is not stored in the array yet. Then the program should display the array content on the console window.
Consult the green sheet and the chapter 3 for assembly instructions for floating point numbers. Here is one instruction that you might use:
c.eq.s $f2, $f4
bc1t Label1
Here if the value in the register $f2 is equals to the value in $f4, it jumps to the Label1. If it should jump when the value in the register $f2 is NOT equals to the value in $f4, then it should be:
c.eq.s $f2, $f4
bc1f Label1
To load a single precision floating point number (instead of lw for an integer), you might use:
l.s $f12, 0($t0)
To store a single precision floating point number (instead of sw for an integer), you might use:
s.s $f12, 0($t0)
To assign a constant floating point number (instead of li for an integer), you might use:
li.s $f12, 123.45
To copy a floating point number from one register to another (instead of move for an integer), you might use:
mov.s $f10, $f12
The following shows the syscall numbers needed for this assignment.
System Call System Call System Call
Number Operation Description
2 print_float $v0 = 2, $f12 = float number to be printed
4 print_string $v0 = 4, $a0 = address of beginning of ASCIIZ string
6 read_float $v0 = 6; user types a float number at keyboard; value is store in $f0
8 read_string $v0 = 8; user types string at keybd; addr of beginning of string is store in $a0; len in $a1
------------------------------------------
C program will ask a user to enter numbers and store them in an array
only if the same number is not in the array yet.
Then it prints out the result array content.
You need to write MIPS assembly code based on the following C code.
-------------------------------------------
void main( )
{
int arraysize = 10;
float array[arraysize];
int i, j, alreadyStored;
float num;
i = 0;
while (i < arraysize)
{
printf("Enter a number:\n");
//read an integer from a user input and store it in num1
scanf("%f", &num);
//check if the number is already stored in the array
alreadyStored = 0;
for (j = 0; j < i; j++)
{
if (array[j] == num)
{
alreadyStored = 1;
}
}
//Only if the same number is not in the array yet
if (alreadyStored == 0)
{
array[i] = num;
i++;
}
}
printf("The array contains the following:\n");
i = 0;
while (i < arraysize)
{
printf("%f\n", array[i]);
i++;
}
return;
}
Here are sample outputs (user input is in bold): -- note that you might get some rounding errors

3.4 code practice question 2 edhesive
script code written in many languages of the best known: ( C#_PHP_HTML)
Answer:
PHP
Explanation:
The best way to answer this question is to interpret it as, which of the three is a scripting language.
Analyzing each of the languages
1. C#
C# is not a scripting language, but instead it is an object-oriented programming language. Also, c# is a compiled language and one of the features of scripting language is that, they are interpreted.
2. PHP
Basically, PHP are used for server side scripting language because it uses scripts and its programs are not for general purpose runtime environment (but instead for special runtime environments).
3. HTML
HTML is neither a programming language, nor a scripting language because its design pattern does not follow that or programming and scripting languages, and it can not perform what an actual programming and scripting language do.
You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???
Along with the encrypted copy, some mysterious person has also given you the following documents:
helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.
hints.txt -- Seems important.
In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:
decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")
Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).

Write a program that lets a maker of chips and salsa keep track of sales for five different types of salsa: mild, medium, sweet, hot, and zesty. The program should use two parallel 5-element arrays: an array of strings that holds the five salsa names and an array of integers that holds the number of jars sold during the past month for each salsa type. The salsa names should be stored using an initialization list at the time the name array is created. The program should prompt the user to enter the number of jars sold for each type. Once this sales data has been entered, the program should produce a report that displays sales for each salsa type, total sales, and the names of the highest selling and lowest selling products.
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String [] salsa = {"Mild","Medium","Sweet","Hot","Zesty"};
int [] number = new int[5];
for(int i = 0;i<5;i++){
System.out.print(salsa[i]+" number: ");
number[i] = input.nextInt();
}
for(int i = 0;i<5;i++){
System.out.println(salsa[i]+" : "+number[i]);
}
int smallest = number[0]; int highest = number[0];
int count = 0;
for(int i = 0;i<5;i++){
if(smallest > number[i]){
smallest = number[i];
count = i;
}
}
System.out.println("Smallest");
System.out.println(salsa[count]+" : "+smallest);
for(int i = 0;i<5;i++){
if(highest < number[i]){
highest = number[i];
count = i;
}
}
System.out.println("Highest");
System.out.println(salsa[count]+" : "+highest);
}
}
Explanation:
This initializes the salsa names
String [] salsa = {"Mild","Medium","Sweet","Hot","Zesty"};
This declares the array for the amount of salsa
int [] number = new int[5];
This iterates through the 5 salsas and get input for the amount of each
for(int i = 0;i<5;i++){
System.out.print(salsa[i]+" number: ");
number[i] = input.nextInt();
}
This prints each salsa and the amount sold
for(int i = 0;i<5;i++){
System.out.println(salsa[i]+" : "+number[i]);
}
This initializes smallest and largest to the first array element
int smallest = number[0]; int highest = number[0];
This initializes the index of the highest or lowest to 0
int count = 0;
The following iteration gets the smallest of the array elements
for(int i = 0;i<5;i++){
if(smallest > number[i]){
smallest = number[i];
This gets the index of the smallest
count = i;
}
}
This prints the smallest
System.out.println("Smallest");
System.out.println(salsa[count]+" : "+smallest);
The following iteration gets the largest of the array elements
for(int i = 0;i<5;i++){
if(highest < number[i]){
highest = number[i];
This gets the index of the highest
count = i;
}
}
This prints the highest
System.out.println("Highest");
System.out.println(salsa[count]+" : "+highest);

Explanation:
Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a program that takes two integer inputs, and outputs the largest magnitude value.
Ex: If the inputs are: 5 7 the method returns: 7
Ex: If the inputs are: -8 -2 the method returns: -8
Answer:
The program in Java is as follows:
import java.util.*;
import java.lang.Math;
public class Main{
public static int maxMagnitude(int num1, int num2){
int mag = num2;
if(Math.abs(num1) > Math.abs(num2)){
mag = num1;
}
return mag;
}
public static void main(String[] args) {
int num1, num2;
Scanner input = new Scanner(System.in);
System.out.print("Enter two integers: ");
num1 = input.nextInt();
num2 = input.nextInt();
System.out.println(maxMagnitude(num1,num2));
}
}
Explanation:
The method begins here
public static int maxMagnitude(int num1, int num2){
This initializes the highest magnitude to num2
int mag = num2;
If the magnitude of num1 is greater than that of num2
if(Math.abs(num1) > Math.abs(num2)){
mag is set to num1
mag = num1;
}
This returns mag
return mag;
}
The main method begins here
public static void main(String[] args) {
This declares num1 and num2 as integer
int num1, num2;
Scanner input = new Scanner(System.in);
This prompts the user for two integers
System.out.print("Enter two integers: ");
This gets input for the first integer
num1 = input.nextInt();
This gets input for the second integer
num2 = input.nextInt();
This calls the maxMagnitude method and prints the number with the highest magnitude
System.out.println(maxMagnitude(num1,num2));
}
6.12 LAB: Warm up: Parsing strings (1) Prompt the user for a string that contains two strings separated by a comma. (1 pt) Examples of strings that can be accepted: Jill, Allen Jill , Allen Jill,Allen Ex: Enter input string: Jill, Allen (2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)
Answer:
Explanation:
The following code is written in Python. It is a loop that asks the user for an input. If it contains a comma then it removes whitespace, splits it into two words, and prints each word seperately, and exits the loop. If it does not contain a comma then it prompts the user for another input.
while True:
string = input("Enter input string: ")
if ',' in string:
string = string.replace(" ", '')
string_split = string.split(',')
print("First word: " + string_split[0])
print("Second word: " + string_split[1])
break
the shadows she fancied has tricked her. what does that mean
Answer: the room had been dark, she had not been able to see him clearly
Explanation:
The word FANCIED means desire or fancied would mean supposed, believed, or imagined.
So it means that she might think that the shadow (assuming the shadow was a person who was invisible) was just her imagination or hallucination but in reality, the shadow (invisible person) tricked her.

What is the function of a bread crumb trial in a website
Answer:
A “breadcrumb” (or “breadcrumb trail”) is a type of secondary navigation scheme that reveals the user's location in a website or Web application. The term comes from the Hansel and Gretel fairy tale in which the two title children drop breadcrumbs to form a trail back to their home.
Explanation:
A breadcrumb or breadcrumb trail is a graphical control element frequently used as a navigational aid in user interfaces and on web pages. It allows users to keep track and maintain awareness of their locations within programs, documents, or websites. Breadcrumbs make it easier for users to navigate a website – and they encourage users to browse other sections of the site. ... You head to their site and end up on The Nestle company history page. Using their breadcrumbs, you can easily navigate back to About Us, History, or even their home page.
