How to reverse a string in c++ using reverse function

#include <iostream>
//The library below must be included for the reverse function to work
#include<bits/stdc++.h> 
using namespace std;

int main() {
  
  string greeting = "Hello";
  //Note that it takes the iterators to the start and end of the string as arguments
  reverse(greeting.begin(),greeting.end());
  cout<<greeting<<endl;
}
