Do...While Loop

The do-while Loop

The do-while loop is like while, but it guarantees the body executes at least once before checking the condition.

int x = 10;

do {
  cout << x << "\n";
  x--;
} while (x > 0);

This is perfect when the first iteration must always happen — for example, showing a menu before asking the user to pick an option.

The condition comes after the body, so remember the semicolon at the end.

int secret = 7;
int guess;

do {
  cout << "Guess: ";
  cin >> guess;
} while (guess != secret);

cout << "Correct!";
