C++ String crend

The crend function represents the end iterator in reverse. In C++, it points to the element before the first character of a string and provides a 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 provides a constant reverse iterator pointing to the end of the string in reverse.

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 instance, we obtained the inverted string by utilizing the 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 instance, we obtained the inverted string that holds numerical values by employing the crend function.
