// Multiplication Table using While Loop
#include <stdio.h>

int main() {
    // Step 1: Declare variables for the user's number and the loop counter.
    int num;
    int i = 1; // Initialize the counter before the loop

    // Step 2: Prompt the user to enter a number.
    printf("Enter an integer: ");

    // Step 3: Read the integer input from the user.
    scanf("%d", &num);

    // Step 4: Print a header for the multiplication table.
    printf("\nMultiplication Table of %d:\n", num);

    // Step 5: Use a while loop to iterate from 1 to 10.
    while (i <= 10) {
        // Step 6: Inside the loop, calculate and print each line.
        printf("%d x %d = %d\n", num, i, num * i);
        // Step 7: Increment the counter manually to avoid an infinite loop.
        i++;
    }

    return 0;
