C Program to find the largest number among three number.

I have used DEV-C++ compiler for debugging purpose. But you can use any C programming language compiler as per your availability.

#include <stdio.h>
int main()
{
    int num1, num2, num3;

    printf("Enter three numbers: ");
    scanf("%d %d %d", &num1, &num2, &num3);

    if( num1 >= num3 && num1 >= num3 ){
    
        printf("%d is the largest number.", num1);
    }
    
    else if( num2 >= num1 && num2 >= num3 ){
        printf("%d is the largest number.", num2);
    } 
    
    else if( num3 >= num1 && num3 >= num2 ){
        printf("%d is the largest number.", num3);
    }        

    return 0;
}

Result:

Enter three numbers: 60

70

80

80 is the largest number.
