C++ Generic Pointer Type- Exercise

The problem with using void* is that it cannot be dereferenced. Thus, to perform useful work on a generic pointer, you must cast it to a standard working type, such as char*.

Use the following code fragment to write and test the memcpy function so that the generic pointer type is cast to char*. This function copies the n characters from the variable based at s2 into the variable based at s1 and works with any two pointer types as actual arguments.

void* memcpy(void* s1, const void* s2, unsigned n){
  char* from = s2, *to = s1;   //uses char type
  ....
}
