Sample C program showing if – else constructs

Below are simple C programs for beginners to learn if-else decision construct.

Example 1: Program to check if a number is odd or even

main (){
       int n;        

       printf("Please enter any number>> ");

       scanf("%d", &n);

       if(n % 2 == 0)
             printf("\n%d is EVEN \n", n);
       else
             printf("\n%d is ODD \n", n);
}

Example 2: Program to check which number is the largest

main (){
       int a, b, c;        

       printf("Please enter 3 numbers of your choice>> ");

       scanf("%d %d %d", &a, &b, &c);

       if(a > b && a > c)
             printf("\n%d is Largest\n", a);
       else if(b > c)
             printf("\n%d is Largest\n", b);
       else
             printf("\n%d is Largest\n", c);
}
