sort() Function in C++

This C++ program demonstrates the sort() algorithm. The program creates a vector of strings, sorts them using sort algorithm without predicate to sort them in default order and with greater predicate to sort them in reverse order and prints it.

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