Answer 1

the return value is void, which mean that you don't want the function to return any value, but in your code you have a return value, that will probably be an issue for your code

Answer 2

You need to return the address of result, not result itself. Then you will need sq_int to be a float pointer. Then you will need to derefercence sq_int in the printf function call. Then it should work.

Answer 3

and how to be with the void pointer
