STL标准库中的大多类都支持用户提供一个自定义的内存分配器,默认使用的是std::allocator,如std::string:typedef basic_string<char, char_traits<char>, allocator<char> > string;如果我们的内存池兼容std::allocator,那么我们就可以使用我们自己的内存池来替换默认的std::
接着来看P2251,它更新了std::span和std::string_view的约束,从C++23开始,它们必须满足TriviallyCopyable Concept。 主流编译器都支持该特性。 最后来看P0448,其引入了一个新的头文件。 大家都知道,stringstream现在被广泛使用,可以将数据存储到string或vector当中,但这些容器当数据增长时会发生「挪窝」的行为,若是不...

If you specified LOCALE(strinf string literal), the compiler uses the runtime function setlocale(LC_ALL "string literal") to determine the name of the compile-time locale. If you do not use the LOCALE compiler option, the macro is undefined. Prior to z/OS V1R9 XL C/C++, the __...
