Display all the lines in unixPasswd that contain at least 10 consecutive lowercase letters. How many names are there in total that meets this criteria?
Answer and Explanation:
To display 10 consecutive lower case letters in Unix, we make use of the commands below. The first command finds the letters in the file and the second command counts them line by line.
$ grep '[a-z]\{10,\}' /unixPasswd/passwd
# this command displays lines with at least 10 consecutive lowercase letters or more than 10 consecutive lowercase letters
$ grep '[a-z]\{10,\}' /unixPasswd/passwd | wc -l
# this command counts the number of lines that has at least 10 consecutive lower case letters or more than 10 consecutive lowercase letters
Note: the unixPasswd is a file in passwd file. The # is used when we want to add comments, is optional here. The $ is a prompt on the terminal that begins a new command.
Using a third-party package of your choice, write a program that reads the contents of a csv file and saves it to an Excel file. The program should take two arguments. The name of the input file and the name of the output file.
Answer:
import pandas as pd
df = pd.read_csv("file_csv")
df.to_excel("file.xlsx", sheet_name = "name_of_sheet")
# or use: with df.ExcelWriter("file.xlsx", mode='a') as file,
#df.to_excel(file, sheet_name= "sheet name")
Explanation:
This python source code uses the pandas package to read csv (comma separated values) file and converts it to an excel file (xlsx) using the read_csv and ExcelWriter methods respectively.
which of the following file formats cannot be imported using Get & Transform?
Answer:
The answer to this question is given below in the explanation section.
Explanation:
In this question, the given options are:
A.) Access Data table
B.)CVS
C.)HTML
D.)MP3
The correct option to this question is D- MP3.
Because all other options can be imported using the Get statement and can be further transformed into meaningful information. But MP3 can not be imported using the GET statement and for further Transformation.
As you know that the GET statement is used to get data from the file and do further processing and transformation.
Write a loop that fills an array int values[10] with ten random numbers between 1 and 100. Write code for two nested loops that fill values with ten different random numbers between 1 and 100.
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
int[] array = new int[10];
int index = 0;
while(index < array.size()){
int number = (rand() % 100) + 1;
for (int i = 0; i < 1; i++) {
array[index] = number;
cout<< "Position "<< index << "of the array = "<< number << endl;
++index;
}
}
}
Explanation:
The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.
Write a for loop to print the numbers 88, 84, 80, ...44 on one line. Expected Output 88 84 80 76 72 68 64 60 56 52 48 44
The solution in python is:
for x in range(88, 43, -4):
print(x, end=" ")

Write a loop that sets each vector element to the sum of itself and the next element, except for the last element which stays the same. Be careful not to index beyond the last element. Ex:Initial scores: 10, 20, 30, 40Scores after the loop: 30, 50, 70, 40The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last element remains the same. Sample program:#include #include using namespace std;int main() { const int SCORES_SIZE = 4; vector bonusScores(SCORES_SIZE); int i = 0; bonusScores.at(0) = 10; bonusScores.at(1) = 20; bonusScores.at(2) = 30; bonusScores.at(3) = 40; for (i = 0; i < SCORES_SIZE; ++i) { cout << bonusScores.at(i) << " "; } cout << endl; return 0;}
Answer:
Add the following lines of code to the already existing code segment
for (i = 0; i < SCORES_SIZE-1; ++i) {
bonusScores.at(i) = bonusScores.at(i) + bonusScores.at(i+1);
}
Explanation:
To do the task in the question, we have to iterate through the vector from the first element i.e. element at index 0 to the second to the last element; i.e. element at last index - 1
We then add each element in this iteration with the next.
This iterates through the vector from 0 to SCORES_SIZE - 1
for (i = 0; i < SCORES_SIZE-1; ++i) {
This adds each vector element with the next
bonusScores.at(i) = bonusScores.at(i) + bonusScores.at(i+1);
}
The above should be added before
for (i = 0; i < SCORES_SIZE; ++i) {
cout << bonusScores.at(i) << " ";
}
Also, I've made other modifications to the program.
Proper import of header filesProper declaration of vector bonusScoresSee attachment for complete source code

What property must be set on a menu item to have the user activate that option by pressing Ctrl C on the keyboard
Answer:
ShortcutKeys
Explanation:
ShortcutKeys is a term used in computing to describe a combination of two or more keys to perform specific actions in a faster way.
Some shortcut keys have been programmed on the operating system of the computer, while a user can also create some through scripting coding.
For example, Ctrl + B is for Bold, while Ctrl + A is for select all.
Hence, to have the user activate the SHORTCUT option by pressing Ctrl C on the keyboard, a SHORTCUTKEYS property must be set on a menu item
In programming languages, ____ is used as a mnemonic representation for the program instruction’s memory address.
Answer:
Assembly language
Explanation:
Assembly language writes instructions in human letters. Every machine language instruction has a corresponding assembly language instruction that means exactly the same thing. Assembly language uses a symbolic form of a program which are capable of:
- readable by human beings (+/-)
- constants, addresses, and names of symbolic instructions
- arithmetic during assembly - calculations of addresses, constants
- synthetic instructions (not supported by our assembler)
- expansion of macroinstructions (not supported by our
assembler)
- assembly instructions (pseudo-instructions)
• memory allocation
• memory initialization
• conditional assembly (not supported by our assembler)
Given two integer arrays, largerArray with 4 elements, and smallerArray with 3 elements. What is the result after this code executes?for = 0; i < 45 ++) { LargerArray) = smallerArray(); A. All of the elements of secondArray will get copied to firstArray. B. Error: The two arrays are not the same size. C. All the elements of firstArray will get copied to secondArray D. Some of the elements of firstArray will get copied to secondArray,
Answer:
A. All of the elements of secondArray will get copied to firstArray.
Explanation:
The correct iteration code is:
for(i =0; i<4;++i) {
largerArray[i] = smallerArray[i];
}
From the question, we understand that the largerArray has a size of 4 elements while the smallerArray has a size of 3 elements
Take for instance largerArray is {1,2,3,4} and smallerArray is {5,6,7}
Next, we analyze the loop
1. for(i =0; i<4;++i) { --->This iterates from index 0 to index 3
2. largerArray[i] = smallerArray[i]; ---- > This assigns the elements of the smallerArray to largerArray.
However, it should be noted that the smallerArray has a maximum index of 2 while the largerArray has a maximum index of 3
The content of largerArray after the iteration will be:
largerArray = {5,6,7,5}
This is so because,
When i = 0
largerArray[0] = smallerArray[0] = 5
When i = 1
largerArray[1] = smallerArray[1] = 6
When i = 2
largerArray[2] = smallerArray[2] = 7
When i = 3
largerArray[3] = smallerArray[0] = 5
Notice that the last iteration refers to smallerArray[0]; this is so because index 3 do not exist in smallerArray. Hence, the index will be returned to the first index of the smallerArray
Taking largerArray as the firstArray and smallerArray as the secondArray.
We can conclude that option A answers the question because all elements in smallerArray is copied to firstArray

An 8-bit ADC has an input range of 0 to 10 volts and an output range of 0 to 255 (called straight binary). What digital value will be returned when an input of 7.5 volts is sampled?
Answer:
converting 191.25 to Binary 110011
Explanation:
Input range = 0 to 10volts
output range = 0 to 255
first we have to determine the resolution
= output range / input range
= 255 -0 / 10 - 0
= 25.5
when an input value of 7.5 volts is sampled
digital equivalent o/p voltage = 7.5 * 25.5
= 191.25
converting 191.25 to Binary 110011

A user invokes an app that writes a file. The app displays a progress bar that shows how much of the file has been written. Just as the progress bar reaches 50%, the battery fails and the device crashes. When the user reboots the device, he or she discovers that less than 20% of the file has actually been written. Explain why the app reported writing 50%. Frame your answer in terms of the design of I/O device drivers.
Answer:
The app reported writing 50% before the battery fails is because while writing, the data is been saved in the secondary memory via a buffer and not directly to the primary memory ( RAM ) and its returned from the secondary memory via the buffer to the primary memory
Explanation:
The app reported writing 50% before the battery fails is because while writing, the data is been saved in the secondary memory via a buffer and not directly to the primary memory ( RAM ) and its returned from the secondary memory via the buffer to the primary memory
What the app displays as a progress bar is from the Buffer, this is because as the developer was designing the app he wanted the data entry to be very fast hence he had to send the file through a buffer with the aid of a workstation he designed. so if the secondary storage is slow in returning the data back to the primary memory as fast as it entered the secondary memory via the Buffer, Then the percentage of the file that would be displayed as written when the system reboots will be less than what the app displayed before the reboot i.e. 20% < 50%

Suppose that you have been asked to create an information system for a manufacturing plant that produces nuts and bolts of many shapes, sizes, and functions. What questions would you ask, and how would the answers affect the database design
Answer:
Following are the solution to this question:
Explanation:
In essence, both issues (relevant) were addressed, that form the design of the system, and all of the information collected and during initial analysis along with all subsequent stages will, in turn, affect the design of the system. Being aware, that perhaps the data is obtained to establish the entities, attributes, or relations. In particular, partnerships, clearly outline, or cardinal-ties are shaped by company policies derived from the creator's information. Example problems and the probable effects on the layout may be:
It will create the file concurrently for all depts, or would like to build and execute the database simultaneously with one dept?
How would the work be to design affect the development process? In other terms, determine the range of the system as well
as its limits about the bottom-up, centralized, or decentralized.
Do you want, and would you like an integrated framework to develop a single module? (Inventory, production, shipping, billing, etc.)
Would you like a product code, output change, and form of controlling the bolts and bolts and dept? Impact: design of the logical and physical server.
Perhaps you'd like to monitor the sources of every lot a raw resources for the nuts and bolts manufacturing? Impact: design of the logical and physical server. Model E-R.
Perhaps you'd like to monitor consumers receiving shipments of bolts and nuts? Impact: design of the logical and physical database. ER model.
Its documents will you demand, or to whom can these documents be transmitted? What specific reporting requirements?
Reactions to such concerns relate to the design, execution, testing, or subsequent functioning of the logical and physical system.
The sensitivity range for an objective function coefficient is the range of values over which the current __________________ remains the same.
Answer:
Optimal solution point
Explanation:
The sensitivity range for an objective function coefficient is the range of values over which the current optimal solution point remains the same.
Additionally, the range of optimality can be defined as the optimality range with respect to an objective coefficient that comprises of the range of values over which a current optimal solution point will always remain optimal.
Hence, the managers supervising various production lines are saddled with the responsibility of focusing on the objective function coefficient for optimal level of output or productivity.

The public static method named evens that takes in 1 argument int a, and returns a String containing all positive even numbers with each separated by a comma is in explanation part.
What is programming?The process of creating a set of instructions that tells a computer how to perform a task is known as programming.
Here's a possible implementation in Java:
public static String evens(int a) {
if (a < 0) {
return "NONE!";
}
StringBuilder result = new StringBuilder();
for (int i = 0; i <= a; i += 2) {
if (i > 0) {
result.append(",");
}
result.append(i);
}
return result.toString();
}
Thus, this method first checks if the argument is negative, and if so, returns the String "NONE!".

Write a Python program string_functions.py that defines several functions. Each function re-implements Python's built-in string methods.1. my_compare(str1, str2): Takes two strings as parameters (str1, str2) and returns a -1 if str1 is alphabetically less than str2, returns a 0 if str1 is alphabetically equal to str2, and returns a 1 if str1 is alphabetically greater than str2. 2. is_char_in(string, char): Takes a string and a character as parameters and returns True if the character is in the string or False if it is not.3. is_char_not_in(string, char): Takes a string and a character as parameters and returns True if the character is NOT in the string or False if it is.4. my_count(string, char): Takes a string and a character as parameters and returns an integer count for each occurrence of the character. For example, if the function takes in 'abracadabra' and 'a', the function should return 5.5. my_endswith(string, char): Takes a string and a character as parameters and returns True if the character is the last character in the string or False if it is not. For example, if the function takes in 'quartz' and 'z', the function should return True. If the function takes in 'quartz' and 'q', the function should return False.6. my_find(string, char): Takes a string and a character as parameters and returns the first index from the left where the character is found. If it does not find the character, return -1. For example, if the function takes in ‘programming’ and ‘g’, it should return 3. Do not use str.find() for this.7. my_replace(string, char1, char2): Takes a string and two characters (char1 and char2) as parameters and returns a string with all occurrences of char1 replaced by char2. For example, if the string is ‘bamboozle’ and char1 is ‘b’ and char2 is ‘t’ then your function should return ‘tamtoozle’.8. my_upper(string): Takes a string as a parameter and returns it as a string in all uppercase. For example, 'victory' would be 'VICTORY'. Hint: Use the ord(c) function to get the ASCII / Unicode code-point. For example, ord('a') returns the integer 97. Use chr(i) function to convert an integer back to a character. For example, chr(97) returns the string 'a'. You cannot use the built-in string function str.upper() for this.9. my_lower(string): Takes a string as a parameter and returns it as a string in all lowercase. Hint: Similar to the previous item, use ord() and chr(). Do not use str.lower() for this. Extra Credit (10 points): my_title(string): Takes a string and returns a string with the first character capitalized for every word. For example, if the input to the function is "I like Python a lot", the function should return the string "I Like Python A Lot".Note- You may not use Python's built-in string methods - e.g., str.find(), str.replace(), str.lower(), lstrip(), startswith(), endswith(), join() … - to implement yours. However, you *should* use them to test your functions to see if they produce the same results. You can do this in the main or in another defined function which is called by the main. You can use all other Python functions.
Answer:
def my_compare(str1, str2):
mylist = sorted([str1, str2])
if str1 == str2:
return 0
elif str1 == mylist[0]:
return -1
elif str1 == mylist[1]:
return 1
def is_char_in(string, char):
if char in string:
return True
return False
def is_char_not_in(string, char):
if char not in string:
return True
return False
def my_count(string, char):
return string.count(char)
def my_endswith(string, char):
return string.endswith(char)
def my_find(string, char):
if char in string:
return string.index(char)
else:
return -1
def my_replace(string, char1, char2):
lst = [i for i in string]
print(lst)
for i, v in enumerate(lst):
if v==char1:
lst[i] = char2
return "".join(lst)
Explanation:
Above are defined functions similar to the string built-in functions in python. To use them, type in the function name and pass in the required arguments. Save the file name as "string_functions" with a ".py" file extension and use the functions in other files by importing all the function as "import string_functions" or import individual functions with "from string_function import 'function_name' ".
