C++ String crbegin

The crbegin function stands for 'reverse beginning'. This function references to the last character of the string.

Syntax

Consider a string str. Syntax would be:

str.crbegin();

Parameter

This function does not contain any parameter.

Return value

This function returns the constant iterator pointing to the last character of the string.

Example 1

Let's see the simple example of crbegin function:

#include<iostream>
using namespace std;
int main()
{
string str =?Lotus Flower?;
for(auto i=str.crbegin();i!=str.end();i++)
{
cout<<*I;
} 
return 0;
}

Output:

rewolF sutoL

This example shows how to reverse the string using crbegin function.

Example 2

#include<iostream>
using namespace std;
int main()
{
list<int> li(1,2,3,4,5);
for(auto i =li.crbegin();i!=end();i++)
{
cout<<*i;
}
return 0;
}

Output:

This example shows how to get the reverse list using crbegin function.
