reversing a string object using the reverse function in algorithm lib

Using the reverse() function directly along with begin() and end() iteration location setting functions of string class object

Learning Objectives

Learning to use reverse() function which is a library function for string objects.
The function needs start and end locations which are passed using the <object>.begin() and object.end() functions.

Code Understanding

#include <algorithm> //This header is required to use the reverse function

string st=”chocolates are tasty”; //Here we declare and initialise a test string

reverse(st.begin(),st.end());
Here we use the reverse function directly with parameters st.begin() and st.end() in order to tell the reverse function that how much part has to be reversed.

cout<<st<<endl;
The original string itself is reversed, so it can now be printed directly.
