In the final step:
💻 C#
// Ask the player to play again or quit.We can approach it the same way we did with the round logic, with a while loop.
But instead of repeating rounds, we’ll repeat the entire game logic.
💻 C#
GamePrint.Box("Welcome to Odds and Evens!");
// Game starts here.
// Player chooses to play with odds or evens.
GamePrint.Input("Choose 1 for Odds or 2 for Evens");
int playerNumberType = GameInput.Number(1, 2);
(...)
// Determine the winner.
if (playerWinCount > computerWinCount)
{
GamePrint.Success("You win the game!");
}
else
{
GamePrint.Success("Computer wins the game!");
}
// Game ends here.And we also need a different condition. The loop stops, only when the player chooses to quit, otherwise it should run forever.
🤖 Pseudocode
while forever
repeat game Logic
if player chooses to quit
exit loopTo create such a loop, we can use true as the
condition.
This makes it impossible to stop by manipulating the condition. Instead, we need to use the break statement to stop the loop and continue on the next line.
