The template code provided is intended to take two inputs, x and y, from the user and print "pass" if one or more of the following is true:
x is not less than 4
y is not greater than 5 and x + y is less than 7
However, when using De Morgan's law to simplify this code, the programmer has made some mistakes. Can you correct the errors so the code functions as intended?
/* Lesson 6 Coding Activity Question 2 */
import java.util.Scanner;
public class U3_L6_Activity_Two{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
int x = scan.nextInt();
int y = scan.nextInt();
if(!((x 5) || x+y > 7))
System.out.println("pass");
}
}
import java.util.Scanner;
public class U3_L6_Activity_Two{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
int x = scan.nextInt();
int y = scan.nextInt();
if(x>=4|| ((y < 5) && ((x+y) < 7))){
System.out.println("pass");
}
}
}
I'm pretty sure this is what you're looking for. Best of luck.
For formatting and readability sake, the given code is re-written as follows:
/* Lesson 6 Coding Activity Question 2 */
import java.util.Scanner; // 1
public class U3_L6_Activity_Two{ // 2
public static void main(String[] args){ // 3
Scanner scan = new Scanner(System.in); // 4
int x = scan.nextInt(); // 5
int y = scan.nextInt(); // 6
if(!((x 5) || x+y > 7)) // 7
System.out.println("pass"); // 8
}
}
The line that needs to be fixed is the if statement in line 7.
As given in the instruction, the code prints "pass" if one or more of the following is true:
i. x is not less than 4. This can be re-written as;
! ( x < 4 )
ii. y is not greater than 5 and x + y is less than 7. This can be re-written as;
! (y > 5) && (x + y < 7)
To have the right operand of ii to have a negation, we can re-write as follows;
! (y > 5) && ! (x + y > 7) (i.e changing the less than sign to greater than and then putting the negation sign (!)). This is great so that the De Morgan's law will be applicable on both sides.
Note:
a. ! is the Java's equivalent way of writing the logical operator NOT
b. && is the Java's equivalent way of writing the logical operator AND
Since one or more of the conditions in (i) and (ii) need to be true before the "pass" is printed, we can combine (i) and (ii) using the OR operator ( || ) as follows;
! ( x < 4 ) || ( ! (y > 5) && ! (x + y > 7) ) ----------------(***)
The De Morgan's laws are very great for making deductions, equivalence and valid proofs when using logical operators.
The laws are as follows;
i. ∼ (P ∧ Q) = ∼ P ∨ ∼ Q
This can be written as;
! (P AND Q) = ! P OR !Q
or in Java like syntax as
! (P && Q) = ! P || !Q
ii. ∼ (P ∨ Q) = ∼ P ∧ ∼ Q
This can be written as;
! (P OR Q) = ! P AND !Q
or in Java like syntax as
! (P || Q) = ! P && !Q
Using these laws, we can simplify our expression in (***) as follows;
! ( x < 4 ) || ( ! (y > 5) && ! (x + y > 7) )
a. Start with the right side i.e ( ! (y > 5) && ! (x + y > 7) )
The De Morgan's law (stated in (ii) above) will remove the negation from both terms in the right side term, change the && to || and then put a single negation to apply to both terms in the bracket to give the following;
! ( x < 4 ) || ! ( y > 5 || x + y > 7 )
b. Now, there are two main terms - ! ( x < 4 ) and ! ( y > 5 || x + y > 7 ) separated by ||
Apply the De Morgan's law (stated in (i) above) to remove the negation from both terms, then change the || to && and then put a single negation to apply to both terms.
! ( x < 4 && (y > 5 || x + y > 7))
The result in b is the simplified version of the condition in the if statement.
The complete and corrected code is therefore written as follows;
/* Lesson 6 Coding Activity Question 2 */
import java.util.Scanner; // 1
public class U3_L6_Activity_Two{ // 2
public static void main(String[] args){ // 3
Scanner scan = new Scanner(System.in); // 4
int x = scan.nextInt(); // 5
int y = scan.nextInt(); // 6
if(! ( x < 4 && (y > 5 || x + y > 7) ) ) // 7
System.out.println("pass"); // 8
}
}

Explanation:
TASK 1 – Work out the cost.
The cost of the trip for each student is a share of the cost of a coach plus the cost of entry to the theme park.
The total cost of the coach will be $550. The entry cost to the park is $30 for each student. The national park gives one free ticket for every ten that are bought, which must be taken into consideration.
Set up a program that:
• stores the cost of the coach
• stores the cost of an entry ticket
• inputs the estimated number of students taking part, this must be validated on entry and an
unsuitable entry rejected
• calculates and outputs the recommended cost per student to ensure the trip does not make a loss.
Write an algorithm to complete Task 1, using either pseudocode, programming statements or a

Write a program with a method called passwordCheck to return if the string is a valid password. The method should have the signature shown in the starter code.
The password must be at least 8 characters long and may only consist of letters and digits. To pass the autograder, you will need to print the boolean return value from the passwordCheck method.
Hint: Consider creating a String that contains all the letters in the alphabet and a String that contains all digits. If the password has a character that isn’t in one of those Strings, then it’s an illegitimate password!
import java.util.Scanner;
public class JavaApplication46 {
public static boolean passwordCheck(String pass){
String alphanum = "abcdefghijklmnopqrstuvwxyz1234567890";
boolean legit = true;
if (pass.length()>= 8){
for(int i = 0; i < pass.length(); i++){
if (alphanum.indexOf(pass.charAt(i)) != -1 && legit != false){
legit = true;
}
else{
legit = false;
}
}
}
else{
legit = false;
}
return legit;
}
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.print("Enter a password: ");
String password = scan.next();
System.out.println(passwordCheck(password));
}
}

Name the type of software which provides the user interface. [1 mark
Explanation:
user interface, also sometimes called a human-computer interface, comprises both hardware and software components. It handles the interaction between the user and the system.
There are different ways of interacting with computer systems which have evolved over the years. There are five main types of user interface:
command line (cli)
graphical user interface (GUI)
menu driven (mdi)
form based (fbi)
natural language (nli)
Assignment 4: Evens and Odds
n = int(input("How many numbers do you need to check? "))
even = 0
odd = 0
for x in range(n):
num = int(input("Enter number: "))
if num % 2 == 0:
print(str(num) + " is an even number.")
even += 1
else:
print(str(num) + " is an odd number.")
odd += 1
print("You entered "+str(even)+" even number(s).")
print("You entered "+str(odd)+" odd number(s).")
This works for me. Best of luck.
The program checks if user supplied integers are even or odd and displays the appropriate value. The program is written thus in python 3 ;
n_check = int(input("How many numbers do you need to check? "))
#number of values user wishes to test
even_count = 0
odd_counts = 0
for n in range(n_check):
num = int(input("Enter number: "))
if num % 2 == 0:
#even numbers leave no remainder when divided by 2
print(str(num) + " is an even number.")
even_counts+= 1
#increase count of even numbers
else:
print(str(num) + " is an odd number.")
odd_counts += 1
print("You entered "+str(even_counts)+" even number(s).")
print("You entered "+str(odd_counts)+" odd number(s).")
#display the number of even and odd numbers entered.

PLS HURRY!!
Look at the image below
Answer:
1. A function can use variables as parameters.
2. A function can have more than one parameter.
3. The definition of a function must come before where the function is used.
Explanation:
The definition of a function can come before or after it is used - I am pretty sure it cannot be placed after the function is being used. It should always come before it is used, so this statement is false.
A function can use variables as parameters - this is true, variables are just labels to hold data.
A function can have more than one parameter - this is true.
A function must have a return value - functions do not always have to return values. It could simply print, so this statement is false.
The definition of a function must come before where the function is used - As said earlier, the definition of functions must come before it is used/called. This statement is true.
