6.3 Deciding the Round Winner

In the last step, we:

_{💻 C#}

// Add the two numbers.
// Check if the sum is odd or even.
// --> Decide the round winner.

If the sum is evens, the winner is the one playing with evens. It can be either the player or the computer. It depends on the player initial choice.

At the beginning, we stored the player’s choice in a variable. That variable holds the value 1 if the player is odds and 2 if evens.

_{💻 C#}

playerSide == 2 // The player is evens.

If the player is evens and the sum is evens, the player is the winner, otherwise, the computer wins the round.

✅ What to Do

• Declare a boolean variable playerIsEvens to store if the player is evens.
• Write an if-else statement that checks if playerIsEvens equals sumIsEvens.
• Use GamePrint.Success or GamePrint.Error to print the correct message in each code block: You win this round! or Computer wins the round!.
• Run the program.
