在C ++中实现断言检查的最好方法是什么？ [英] What is the best way of implementing assertion checking in C++?

问题描述

我需要做的是在我的代码中使用有用的断言。MFC很容易，我只是使用ASSERT（东西）。

非MFC方式是什么？

编辑：停止断言assert.c而不是我的文件调用assert（）？

编辑：< assert.h> & < cassert>

？

接受答案 ，我希望我可以接受一个以上的答案（或有人会把他们所有）。所以答案被授予Ferruccio（第一个答案）。

解决方案

  #include< cassert> 
 
 assert（something）; 
  

并且对于编译时检查，Boost的静态断言非常有用：

  #include< boost / static_assert.hpp> 
 
 BOOST_STATIC_ASSERT（sizeof（int）== 4）; //如果int不是32位则编译失败
  

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).

解决方案

#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
