Having issues learning C++

Question

Okay so i am in the middle of learning C++ and i have come across an error i don't understand. My code is as follows...

#include <iostream>
#include <string>
using namespace std;
int main() {
    int x;
    cin >> x;
    if (x == 1) {
        cout << "Red" << endl;
    }
    else if (x == 2) {
        cout << "blue" << endl;
    }
    else if (x == 3) {
        cout << "green" << endl;
    }
    else if (x == 4) {
        cout << "orange" << endl;
    }
    else if (x == 5) { 
        cout << "pink" << endl; 
    }

    string y;
    getline(cin, y);

    return 0;
}

So my issue is that the it seems to skip past the getline(cin, y) at the end. My guess is that it is just something really obvious but i cant see anything. Thanks in advance for any help.
