Beginner Problems

HI I have a question to ask. I wrote this program to check if a user imput "Hello World" correctly, but when I tested it out, correct input is also marked as wrong. Can someone help me with this?

Code:

#include <iostream>
#include <string>
using namespace std;
int main() {
    string s;
    cin >>\ s;
    getline (cin, s);
    if (s == "Hello World"){
        cout << "OK";
    }
    else {
        cout << "Wrong Answer";
    }
 
}

 

I tried that, but the program still doesn't run correctly. When I enter Hello World, it outputs wrong answer

 

I had same problem friends thanks for solving

 

simply use
cin>> s;
no need to use getline if you are taking string as a datatype
and take care that C++ is case sensitive so in input, it should be Hello World only

 

Got similar problems, thanks for information, hope it will help me
