C++ basic string input and output

Question

Alright, so I've got a simple online programming assignment that's checked by an automatic grading thingy. Most have been pretty easy, but I can't get this assignment to work. Here's the prompt and my code. I have a feeling I'm missing something fairly simple. Thanks for your help.

Students just took a short, two question, multiple choice quiz. Both questions needed to >be answered correctly to receive credit. As their grader, you must determine whether >students got credit or not. The correct answers were A and D.

Input

The students' answers, sepated by a space.

Output

"Credit" or "No credit"

Example

Input: A C

Output: No credit

My code:

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string input;
    cin >> input;
    if (input == "A D")
    {
        cout << "Credit";
    }    
    else 
    {
        cout << "No credit";
    }
    
    return 0;
}

You should use a string compare function.

std::cin will stop searching for input when it hits a new line \n or whitespace. In order to get the entire line of input, use std::getline:

std::string input;
std::getline(std::cin, input);
