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:

You can nest your switch statements for each expression, such as

switch(a)
{
  case 'A':
    switch(b)
    {
      case 0: // do something with A0
        break;
      case 1: // do something with A1
        break;
      ...
    }
    break;

  case 'B':
    switch(b)
    {
      case 0: // do something with B0
        break;
      ...
    }
    break;
  ...
}

As you can see, this has the potential to get very ugly very quickly. If you have to branch based on combinations of values, then you're probably better off keeping the current structure.
