8.1 Announce the Game Winner

In the next step, we need to:

_{💻 C#}

// Announce the game winner.

The winner is the first one to reach two wins.

The while loop stops when it happens, and the execution continues on the next line. It’s there where we’ll declare the game winner.

We know that for the program to reach the line after the while loop, one of the players win count should be 2.

One approach could be to check the value of the player win count. If it’s 2, than the player is the winner, else it’s the computer.

_{🤖 Pseudocode}

if playerWinCount is equal to 2
    Player wins the game
else 
    Computer wins the game

The only downside is that if we decide to change the amount of wins needed, there is one extra place to change it.

So, there is a better comparison to declare the game winner: it’s the one with the higher win count.

If the player win count is greater than the computer, the player wins, else the computer wins.

_{🤖 Pseudocode}

if playerWinCount is greater than computerWinCount
    Player wins the game
else 
    Computer wins the game

✅ What to Do

• Write an if-else that checks if playerWinCount is greater than computerWinCount.
• Use GamePrint.Success and GamePrint.Error to print the game winner: You win the game! or Computer wins the game!.
• Run the program.
