String Class - end() iterator function

#1

for(string::iterator it=s1.end();it!=s1.begin();it–)
{
cout<<(*it)<<endl;
}

If I write this code ‘m’ that is the first letter of string is not getting printed.
What changes are needed?

hi @official.shree31

#include <iostream>
using namespace std;
int main() {
    string s1 = "Hello World";
    for(string::iterator it=s1.end();it!=s1.begin();it--)
    {
    cout<<(*it);
    }
}

suppose this is the code then its o/p will be --> dlroW olle
there will be a space in beginning bcoz ur loop is starting from s1.end(), and it wont print the first character bcoz ur loop is going till it != s1.begin() where it skips the first character…
if u want to print the first character then run the loop till it!=s1.begin()-1
hope it clears ur doubt
