Answer:
The code segment was written in Python Programming Language;
The while loop equivalent is as follows:
i = 1
j = 1
while i < 6:
while j < i + 1:
print('*',end='')
j = j + 1
i = i + 1
print()
Explanation:
(See attachment for proper format of the program)
In the given lines of code to while loop, the iterating variables i and j were initialised to i;
So, the equivalent program segment (in while loop) must also start by initialising both variables to 1;
i = 1
j = 1
The range of the outer iteration is, i = 1 to 6
The equivalent of this (using while loop) is
while ( i < 6)
Not to forget that variable i has been initialized to 1.
The range of the inner iteration is, j = 1 to i + 1;
The equivalent of this (using while loop) is
while ( j < i + 1)
Also, not to forget that variable j has been initialized to 1.
The two iteration is then followed by a print statement; print('*',end='')
After the print statement has been executed, the inner loop must be close (thus was done by the statement on line 6, j = j + 1)
As seen in the for loop statements, the outer loop was closed immediately after the inner loop;
The same is done in the while loop statement (on line 7)
The closure of the inner loop is followed by another print statement on line 7 (i = i + 1)
Both loops were followed by a print statement on line 8.
The output of both program is

Explanation:
The following code is written in Java and like requested prompts the user for a number to continue or a letter to exit. Then loops and keeps adding all of the numbers to the sum variable and adding 1 to the count for each number entered. Finally, it prints the sum and the average using printf and the variables.
import java.util.Scanner;
class Examine1 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int sum = 0;
int count = 0;
System.out.println("Enter a number to continue or a letter to exit.");
while(in.hasNextInt()) {
System.out.println("Enter a number:");
sum += in.nextInt();
count += 1;
}
System.out.printf("The sum is %s.%n", sum);
System.out.printf("The average is %s.", (sum / count));
}
}
