C++ vector::push_back() Function - The C++ vector::push_back() function is used for pushing element from the back of the vector. When the final or current element is entered into the vector, any new element is added from the end of the vector, increasing
append():可以使用append()来追加C++ string类型。 push_back():不允许使用push_back()来追加C++ string类型。 // CPP code for comparison on the // basis of appending Full String #include <iostream> #include <string> using namespace std; // Function to demonstrate comparison among // +=...
