Given an int variable that has already been declared and initialized to a positive value

Given an int variable that has already been declared and initialized to a positive value, use a while loop to print a single line consisting of ?? ?asterisks. Use no variables other than ??.

The Correct Answer and Explanation is :

To print a single line consisting of n asterisks using a while loop in C, you can use the following code:

#include <stdio.h>

int main() {
    int n = 5; // Example positive value for n
    while (n > 0) {
        printf("*");
        n--;
    }
    printf("\n"); // Move to the next line after printing all asterisks
    return 0;
}

Explanation:

  1. Initialization: he variable n is initialized to a positive integer value, representing the number of asterisks to be printed. In this example, n is set to 5.
  2. While Loop Condition: he while loop continues to execute as long as n is greater than 0. This ensures that the loop runs exactly n times.
  3. Printing Asterisks: ithin the loop, printf("*"); outputs a single asterisk without moving to a new line.
  4. Decrementing n: fter printing an asterisk, n is decremented by 1 using n--;. This reduces the value of n by one in each iteration, bringing it closer to the loop termination condition.
  5. Loop Termination: nce n reaches 0, the while loop condition n > 0 becomes false, and the loop exits.
  6. Newline Character: fter exiting the loop, printf("\n"); is used to move the cursor to the next line. This is optional but ensures that any subsequent output starts on a new line.
    Key Points:
  • Single Variable Usage: he task specifies using no variables other than n. In this solution, n serves both as the loop counter and the determinant of the number of asterisks to print.
  • Loop Mechanics: he while loop is appropriate here because the number of iterations is determined by the initial value of n. The loop decrements n with each iteration until it reaches zero, ensuring that exactly n asterisks are printed.
  • Output Control: y not including a newline character within the loop’s printf statement, all asterisks are printed on the same line. The newline character is added after the loop to finalize the output line.
    his approach efficiently prints a specified number of asterisks in a single line using a while loop and adheres to the constraint of using only the variable n.
