    cin.get()

    another cin. question but i was wondering exactly how this worked because on this code from the tutorial....

    Code:
    #include <iostream>
    
    using namespace std;
    
    void playgame();
    void loadgame();
    void playmultiplayer();
    	
    int main()
    {
      int input;
      
      cout<<"1. Play game\n";
      cout<<"2. Load game\n";
      cout<<"3. Play multiplayer\n";
      cout<<"4. Exit\n";
      cout<<"Selection: ";
      cin>> input;
      switch ( input ) {
      case 1:            // Note the colon, not a semicolon
        playgame();
        break;
      case 2:            // Note the colon, not a semicolon
        loadgame();
        break;
      case 3:            // Note the colon, not a semicolon
        playmultiplayer();
        break;
      case 4:            // Note the colon, not a semicolon
        cout<<"Thank you for playing!\n";
        break;
      default:            // Note the colon, not a semicolon
        cout<<"Error, bad input, quitting\n";
        break;
      }
      cin.get();
    }
    ...I have to put in cin.get inbetween cout<< and break inorder for it to work (yes i know the methods are undifined but in my actual code i made it a funcional program)

    Just put a cin.ignore() after the "cin >>" statement. It leaves a newline in the buffer which you have to remove before the final cin.get(), which is why it's been closing on you.
