make_pair(T1&&x, T2&&y); (since C++20) Creates astd::pairobject, deducing the target type from the types of arguments. Given typesstd::decay<T1>::typeasU1andstd::decay<T2>::typeasU2, the types/*V1*/and/*V2*/are

若模式[pat_first,pat_last)为空,则返回std::make_pair(first, first)。 否则,返回一对迭代器,指向[first,last)中所定位的与[pat_first,pat_last)按pred的定义比较相等的子序列的首及尾后一位,否则返回std::make_pair(last, last)。 注解 示例 ...
