Syntax error in using iterators it shows that i was not declared

#1 
for(auto i = s.begin();i!=s.end();i++)
{
	cout<<(*i)<<endl;
}

when i did this it gives me error that i is not declared in this scope

#2

@mananrasool2 hey it is not showing any error . i think you have forgot to declare the header file in which string class come . see this code

#include <bits/stdc++.h>
using namespace std;
int main() {
string s = “Hello World!”;
for(auto i = s.begin();i!=s.end();i++)
{
cout<<(*i)<<endl;
}
}
