Question

By that I mean, what do I need to do to have useful assertions in my code?

MFC is quite easy, i just use ASSERT(something).

What’s the non-MFC way?

Edit: Is it possible to stop assert breaking in assert.c rather than than my file which called assert()?

Edit: What’s the difference between <assert.h> & <cassert>?

Accepted Answer: Loads of great answers in this post, I wish I could accept more than one answer (or someone would combine them all). So answer gets awarded to Ferruccio (for first answer).

Answer 1

#include <cassert>  assert(something); 

and for compile-time checking, Boost’s static asserts are pretty useful:

#include <boost/static_assert.hpp>  BOOST_STATIC_ASSERT(sizeof(int) == 4);  // compile fails if ints aren't 32-bit
