remove() Function in C++

This C++ program demonstrates the remove() algorithm. The program creates a vector of strings and removes an element using the remove algorithm from the algorithm library.

Here is the source code of the C++ program which demonstrates the remove() algorithm. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.
