Help with while loops skipping cin input.

[KingSecrets]

So I am working on a little project to help me strengthen my coding skills and I am having some issues with while loops. Whenever my program gets to this snippet of code it goes crazy.

How can I make this run better?

    if(playerrow == slime0row && playercol == slime0col){
        while(slime0dead == false){
            cout << "Slime encountered! What will you do?" << endl;
            cout << " W-Attack!   S-Defend   A-Escape   F-Use Item" << endl;
            cout << ">>";
                cin >> slime0encounter;
                switch(slime0encounter){
                    case 'W':
                        slime0HP - playerATT;
                        cout << "You hit the slime for " << playerATT << " damage." << endl;
                        break;
                    case 'S':
                        break;
                    case 'A':
                        break;
                    case 'F':
                        break;
                    default:;



                }

        }
    }

you probably have a cin before the while loop.

What happens is that when you enter the input and press ENTER for the first input, cin , takes the input and leaves '\n' in the input buffer.

It is this '\n' that is inputted in the next call to cin .
To fix this, after the first call to cin , add the line cin.ignore() to ignore the next character which is '\n' .

I'm a little confused with how to do this.

I added the rest of my code so far, hope this helps.

EDIT: the code I'm having the issue with starts on line 132
