因此cpp 14建议可以通过另一个简单的符号表示该内容。也就是type trait variable templates的概念。 直到cpp 17才在正式标准中进行了全面的完善。 // cpp14 template< bool B, class T = void > using enable_if_t = typename enable_if<B,T>::type; // cpp17 template< class T > inline constexpr b...

An inline functionor inline variable(since C++17)has the following properties: The definition of an inline functionor variable(since C++17)must be reachable in the translation unit where it is accessed (not necessarily before the point of access). ...
inline是编译时展开,必须有实体; static属于class自己的,也必须有实体; virtual函数基于vtable(内存空间),constructor函数如果是virtual的,调用时也需要根据vtable寻找,但是constructor是virtual的情况下是找不到的,因为constructor自己本身都不存在了,创建不到class的实例,没有实例,class的成员(除了public static/protected ...
#include<iostream>#definePRINT_VAR(x)std::cout<<x<<std::endl;voidfoo(){#pragma cppcheck-suppress unusedVariable int a=10;PRINT_VAR(a);} 调整Cppcheck配置:你可以调整Cppcheck的配置文件或命令行参数,以更好地处理宏。例如,使用--inline-suppr选项可以启用内联抑制。
