有没有办法将模板函数的参数类型限制为仅指针或随机访问迭代器?
假设我正在开发一个仅适用于随机可访问容器的排序功能.我正在寻找一种方法来抛出编译时错误,如果用户通过非随机访问迭代器.
#include <type_traits>
#include <iterator>
template <class Iterator> void mySort(Iterator begin, Iterator end){
/*The below condition must be true if the 'Iterator' type is a pointer
or if it is of Category random_access_iterator_tag. How to make such check?*/
static_assert(some condition, "The mySort() function only accepts random access iterators or raw pointers to an array.\n");
for (Iterator it = begin; it != end; ++it){
/*Some kind of sorting is performed here, which
uses arithmetic operators + and - in the …Run Code Online (Sandbox Code Playgroud)
