The reason why it doesn’t is outside the scope of this article.Unit testing first steps:If the function under test uses any pointers, either in the parameters or via accessed global data, inspection must be made. It is necessary to know what the code is doing....
对C来说,指针、无越界检查等等是一切痛苦的根源;但这些痛苦并不是白白付出的。 可以和汇编比效率(甚至可以做到“编译器自动优化的代码比80%汇编高手手工优化的汇编代码都好”),就是这些付出所应得的收获。 事实上,任何一门设计合理的语言,给你的限制或提供的什么特性,都不是没有好处/代价的。 准备在哪方面付出...
1、c+中vector的用法(The use of vector in c+)C+s built-in array supports the mechanism of containers, but it does not support the semantics of container abstractions. To solve this problem, we implement such a class ourselves. In standard C+, container vectors (vector) are used. The ...

就是这样了!现在我们可以保存类成员的信息,并且可以轻松地按照自己的方式推导某对象的类型。 这是一个示范项目的链接,该项目是使用Visual Studio 2010编译的。我确定稍作修改就可以在GCC中编译,但是我不想示范了,因为我太困了!这是该程序的输出结果。格式是<类型><大小>。如果是对象的话,会输出其成员和它们的偏...
