C Program to Find the Largest Number Among Three Numbers

#include <stdio.h>

int main() {

    double n1, n2, n3;

    printf("Enter three different numbers: ");

    scanf("%lf %lf %lf", &n1, &n2, &n3);

    // if n1 is greater than both n2 and n3, n1 is the largest

    if (n1 >= n2 && n1 >= n3)

        printf("%.2f is the largest number.", n1);

    // if n2 is greater than both n1 and n3, n2 is the largest

    if (n2 >= n1 && n2 >= n3)

        printf("%.2f is the largest number.", n2);

    // if n3 is greater than both n1 and n2, n3 is the largest

    if (n3 >= n1 && n3 >= n2)

        printf("%.2f is the largest number.", n3);

    return 0;
