Each concept is a predicate, evaluated at compile time, and becomes a part of the interface of a template where it is used as a constraint: Run this code #include <cstddef> #include <concepts> #include <functi
相当于强制写 concept 或 enable_if，因此报错信息更友好。
Images are an orthogonal concept to threads, such as those provided by C++11 or OpenMP. Threads are used for shared memory programming where each thread has immediate access to the address space of a single process and possibly some thread-local storage to which only it has access. Images...
另外,由于STL是基于模板,内联函数的使用使得生成的代码短小高效; 从逻辑层次来看,在STL中体现了泛型化程序设计的思想,引入了诸多新的名词,比如像需求(requirements),概念(concept),模型(model),容器(container),算法(algorithmn),迭代子(iterator)等。与OOP(object-oriented programming)中的多态(polymorphism)一样,泛...

New keywords requires and concept have been added to the Microsoft C++ compiler. If you attempt to use either one as an identifier in /std:c++20 or /std:c++latest mode, the compiler raises C2059 to indicate a syntax error.Constructors as type names disallowed...
