Keep in mind shorter is not certainly better. On the other hand if your architecture and you are using very simple C compiler the case/switch might overflow the I-cache (so function pointers will perform better). Pointer sure optimizes performance, but it is hardly noticeable here because you use small sized variables (not like a gigantic photo that would use MBs of memory). Using those two values and operand, it will perform Arithmetic Operations. Not the answer you're looking for? two numbers on which the operation is to be performed and what operation is to be performed. Maybe you can use that instead of the forbidden if. Step 5.
