C++ String crend

The crend function stands for reverse end. Icpp tutorials to the first character of string and returns constant reverse iterator.

Syntax

Consider a string s. Syntax would be:

const_reverse_iterator itr=s.crendO;

Parameter

It does not contain any parameter.

Return value

It returns a constant reverse iterator to the reverse end of the string.

Example 1

Let's see a simple example.

#include<iostream>
using namespace std;
int main()
{
	string str="C Programming";
	for(string::const_reverse_iterator itr=str.crbegin();itr!=str.crend();++itr)
	cout<<*itr;
	return 0;
}

Output:

gnimmargorP C

In this example, we got the reverse string using crend function.

Example 2

Let's see another simple example.

#include<iostream>
using namespace std;
int main()
{
	string num="12345";
            for(string::const_reverse_iterator itr=num.crbegin();itr!=num.crend();++itr)
	cout<<*itr;
	return 0;
}

Output:

In this example, we got the reverse string containing integer values using crend function.
