// Find Largest Among Three (if-else if-else)
#include <stdio.h>

int main() {
    int num1, num2, num3;

    // Step 1: Prompt user for input
    printf("Enter three numbers: ");

    // Step 2: Read the three numbers from user
    scanf("%d %d %d", &num1, &num2, &num3);

    // Step 3: Use if-else if-else ladder to find the largest
    if (num1 >= num2 && num1 >= num3) {
