How do I stop my loop from skipping getline

I'm trying to do an exercise on vectors, and iterators. I tried searching on google but not much luck into my specific problem.

"Write a program using vectors and iterators that allows a user to maintain a list of his or her favorite games. The program should allow the user to list all game titles, add a game title, and remove a game title."

When I enter in y or Y it starts the loop over, but skips over my getline statement. Is it something still being stored in the input buffer? If so, how do I rectify that, and where is the source of the problem?

Here's the code so far:

Code:

#include <cstdlib>
#include <iostream>
#include <vector>
#include <algorithm>
#include <string>

using namespace std;

int main(void)
{
    vector<string> GAME_TITLE_VECTOR;
    vector<string>::iterator i;
    string GAME_TITLE;
    char AGAIN = 'y';
    
    cout << "\tWelcome to the favorite video game program!" << endl;
    cout << "\tThis program stores your video game into what's called a vector\n\tand shows what you've entered in so far!" << endl;
    
    cout << endl;
    while ((AGAIN == 'y') || (AGAIN == 'Y'))
    {
    
          cout << "\n\nEnter one of your favorite video games!\n";
          getline (cin,GAME_TITLE);
    
          cout << "So far, you've entered:\n";
    
          GAME_TITLE_VECTOR.push_back(GAME_TITLE);
    
          for (i = GAME_TITLE_VECTOR.begin(); i != GAME_TITLE_VECTOR.end(); ++i)
          {
               cout << *i << endl;
          }
          cout << "\nWould you like to enter another title? ";
          cin >> AGAIN;
    }
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

Put a cin.ignore() after the cin >> AGAIN.
And btw, it's usually considered bad practice to use upper case for variables (it's usually reserved for macros).

Thanks, that fixed the problem. And thank you for the tip as well. I'll make a note of it.
