Find Largest of Three Numbers in C

Find the Largest of Three Numbers in C

This C program takes three numbers as input and determines the largest among them. Here's the code:

#include <stdio.h>

int main() {
    int a, b, c;

    // Input the numbers
    printf("Enter the first number: ");
    scanf("%d", &a);
    printf("Enter the second number: ");
    scanf("%d", &b);
    printf("Enter the third number: ");
    scanf("%d", &c);

    // Determine the largest number
    if (a >= b && a >= c) {
        printf("The largest number is %d\n", a);
    } else if (b >= a && b >= c) {
        printf("The largest number is %d\n", b);
    } else {
        printf("The largest number is %d\n", c);
    }

    return 0;
}

Explanation

The program starts by including the <stdio.h> header file to use the input and output functions.

In the main function, we declare three integer variables: a, b, and c.

We then prompt the user to enter three numbers and read them using scanf.

The program uses a series of if-else statements to compare the numbers:

• If a is greater than or equal to both b and c, a is the largest.
• If b is greater than or equal to both a and c, b is the largest.
• If neither a nor b is the largest, then c must be the largest.

The largest number is then printed to the console.
