Switch case or conditional operator?
I think you could try something like this:





switch( (a - 1) / 15){


case 0: return 'B';


case 1: return 'I';


case 2: return 'N';


case 3: return 'G';


case 4: return 'O';


default: return '0';


}





This relies on the quirk that if you use the / operator between integers it always returns an integer (with the part after the decimal point simply cut off).





I haven't checked it, but I think it's perfectly correct.
