c++ - What type of loop would I wrap around this statement? -

for reason i'm getting extremely confused type of loop should wrapping around switch statement. if have switch statement below , want user able keep inputting keystroke until hits 1 of cases type of loop best use this?

thanks,

int input;  cin >> input;      switch( input ) {     case 1:         playgame();         break;     case 2:         loadgame();         break;     case 3:         multiplayer();         break;     case 4:         cout << "thanks, exitting \n";         break;     default:         cout << "error \n";         cin >> input;         break; } 

there missing stop condition.

int input = 0; // make habit of initialising variables bool again = true; while(again) { // use input != 4 (stop value) cin >> input;  ... case 4: // magic numbers bad, maybe use enum cases.     cout << "thanks, exiting \n";     again = false; // <----- else wont out.     break; ... }
