在C++中删除类型名称的名称空间

#include<iostream>
#include<vector>
#include <type_traits>

int main() {
    using T = const std::vector<int>&;
    using U = std::remove_cvref_t<T>;

    std::cout << "Original type: "<< typeid(T).name()<< std::endl;
    std::cout << "Removed type: "<< typeid(U).name()<< std::endl;

    return 0;
}

Original type: PKSt6vectorIiSaIiEE
Removed type: St6vectorIiSaIiEE
