template 是 c++ 相当重要的组成部分,堪称 c++语言的一大利器。在大大小小的 c++ 程序中,模板无处不在。c++ templates 作为模板学习的经典书籍,历来被无数 c++学习者所推崇。第二版书籍覆盖了 c++ 11 14 和 17 标准,值得程序猿们精读学习,特此整理学习笔记,将每一部分自认为较为重要的部分逐条陈列,并对少数错误...

The idea of template specialization is to override the default template implementation to handle a particular type in a different way. For instance, while most vectors might be implemented as arrays of the given type, you might decide to save some memory and implement vectors of bools as a ...

template <typename InputIterator, typename OutputIterator> OutputIterator copy(InputIterator first, InputIterator last, OutputIterator result) { while (first != last) *result++ = *first++; return result; } Using the genericcopy()function, we can now copy elements from any kind of sequence, inc...
Previously, if the compiler detected that a specialization of a function template would have an abstract class type instance as a function parameter, then that specialization would be considered ill-formed. It wouldn't be added to the set of viable candidate functions. In C++20, the check for...
