7.3 Playing Multiple Rounds

Let’s handle the second step - playing consecutive rounds until one player wins at least two times.

To repeat the round logic, we need a while statement.

🎓 Learn

The condition, in this case, is one of the players winning two times.

Which is the same as saying, we’ll play new rounds while both win counts are less than two.

As soon as one of the win counts reaches two, the while loop stops and the game is over.

🤖 Pseudocode

while playerWinCount is less than 2 and computerWinCount is less than 2
    Repeat the round logic

We already covered how to create a condition using a comparison.

But, in this case we have a compound condition made of two comparisons. Both need to be true for the condition to be true.
