Answer 1

Here's a simple example:

#include 

int main() {
    int x;
    x = 6;
    if (x % 2 == 0) {
        printf("Divisible by two\n");
    }
    else if (x % 3 == 0) {
        printf("Divisible by three\n");
    }
    else {
        printf("Not divisible by two or three\n");
    }
    return 0;
}

Prints

Divisible by two

NOT

Divisible by two
Divisible by three
