The sample declares an empty vector of integers. It adds three integers to the vector, and then deletes one. Finally, it generates the remaining elements in the vector.ExampleCopy // Pushpop.cpp // compile with: /EHsc // Illustrates how to use the push and pop member // functions of...

The size of the vector can be reduced by using different built-in functions of C++. The pop_back() function is one of them. It is used to remove the last element of the vector from the back and reduce the size of the vector by 1. But the last element of the vector is not ...

The C++ vector::pop_back() function is used to remove the final element out of the vector from the back and shrink it size by one unit. The time complexity of the pop_back() function is constant.The final element in the vector is not permanently deleted like the erase() function. ...
