C++ String rend()

The rend() function stands for reverse end. This function points to the first character of the string.

Syntax

Consider a string 'str' and reverse iterator 'ritr'. Syntax would be:

reverse_iterator ritr = str.rend();

Parameter

This function does not contain any parameter.

Return value

It returns a reverse iterator pointing to the beginning of the string.

Example

Let's see the simple example.

#include<iostream>
using namespace std;
int main()
{
	string str="Hello World";
	for(string::reverse_iterator itr=str.rbegin();itr!=str.rend();++itr)
	cout<<*itr;
	return 0;
}

Output:
