有影响的,所以经常在发行版本中,assert 都会被关掉。 assert 的关键在于判断 expression 的逻辑真假,如果为 false,就会在 stderr 上面打 印一条包含“表达式,文件名,行号”的错误信息,然后调用 abort 结束整个程序。 #include<iostream> #include<assert.h> ...
问static_assert导致程序不编译,即使断言位于函数模板的头中EN随着 C++ 11/14/17 标准的不断更新,C++ 语言得到了极大的完善和补充。元编程作为一种新兴的编程方式,受到了越来越多的广泛关注。结合已有文献和个人实践,对有关 C++ 元编程进行了系统的分析。首先介绍了 C++ 元编程中的相关概念和背景,然后利用科学...

如果没有static_assert,您可以执行以下操作:static_assert可用于禁止使用delete关键字,方法如下:#define...
