How do I transform an IF statement with 2 variables onto a switch function using C?

Question

I have an IF-statement that I want to transform into a Switch-statement... But it has 2 variables! Is it possible to do it on C?

It is a rock, paper, scissors game:

Answer 1

#include 
#include 

#define PAIR(X,Y) (X<<8)|Y

int main()
{
    char play1, play2;

    printf("\nPlayer 1 - Enter your Play: ");
    scanf ("%c", &play1);
    printf("\nPlayer 2 - Enter your play: ");
    scanf (" %c", &play2); 

    switch (PAIR(play1, play2)) {
        case PAIR('R','P'):
            printf ("Paper wins!\n");
            break;
        case PAIR('R','S'):
            printf ("Rock wins!\n");
            break;
        case PAIR('R','R'):
            printf ("Draw!\n");
            break;
        default: //any thing else
            printf ("Default!\n");
            break;
    }
}
