reverse() Function in C++

This C++ program demonstrates the reverse() algorithm. The function reverse() takes two iterators as parameters and reverses the order of the elements of the container. The program creates a string array and reverses the order of the strings.

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

$ a.out
Original order : 1. George  2.  John  3.  Lucy  4. Alice  5.   Bob  6. Watson  
Reversing the order ... 
Reversed order : 1. Watson  2.   Bob  3. Alice  4.  Lucy  5.  John  6. George
