How to store various types of function pointers together?

Question

Normal pointers can be stored using a generic void*. e.g.

void* arr[10];
arr[0] = pChar;
arr[1] = pINt;
arr[2] = pA;

Answer 1

Use a union of your function pointer types, this works in both C and C++ and assures sufficient storage for the pointers (which are likely the same size, still...)
