The push_back() function is one of the ways to insert a new element at the end of the vector that increases the size of the vector by 1. This function is useful when one element is required to add to the vector. If the data type of the vector does not su

In this case, we demonstrate a back inserter to append elements at the end of the container. Notice that back inserters can be applied to the containers that have the push_back member function. The following example code shows how to apply the std::fill_n algorithm to the vector container...
