How to resolve “conflicting types error” in C?

Question

For the following C code (for swapping two numbers) I am getting the \"conflicting types\" error for swap function:

#include 
#includ         


        

Answer 1

First off, the actual error message wouldn't hurt.

Secondly, making buffer of [size] only works on some compilers (that's a new feature, not all compilers have it yet). Are you sure yours does?

Thirdly, you need to declare swap before calling it. Add a prototype at the top of the file:

void swap(void *p1,void *p2,int size);
