can sum1 plsss check if my coding is right?

Answer 1

I am sorry but it's not right, realdiv() makes no sense with that prototype, I am making it compilable: http://ideone.com/22DiK

Hope this helps

Answer 2

All of the function calls in the switch statement in main aren't right. A function call consists of the the function name, and arguments/parameters in a comma separated list inside parentheses. The arguments need to match the function's header. So for case 1:

c = add( a, b );
