The **`string::crend()` function** returns the iterator that points to the first character in the string. It is used to traverse the string in reverse order. 

Figure 1 shows the visual representation of the `crend()` function.

# Header file
This function requires a header file:
```c
#include <string>
```

# Syntax
```c
string.crend()
```

# Return value
**`crend()`** returns the iterator pointing to the first character in the string.

# Example
The example below shows how we can use `crend()` to iterate the string in reverse order.


#include <iostream>
using namespace std;
//Header File
#include <string>

int main(){
  //string declared
  string STR="EDPRESSO";
  cout<<"The reverse order of string "<<STR<<": ";
  //iterator is being checked against crend() (first character) inorder to iterate the string in reverse 
  for (auto iterator=STR.crbegin(); iterator !=STR.crend(); iterator++ )
    cout<<*iterator;
}

What is string::crend() in C/C++?

Iterate the string in reverse order with string::crend(), returning an iterator to the first character.
