7.1 Identify the Round Logic

The next step states that:

💻 C#

// Repeat rounds until one of the players wins two times.

The following statements represents a single round:

💻 C#

// Player enters a number between 1 and 2.
GamePrint.Input("Choose a number between 1 and 2");
int playerNumber = GameInput.Number(1, 2);

GamePrint.Message("You chose: " + playerNumber);

// Computer randomly generates a number between 1 and 2.
int computerNumber = GameRandom.Number(1, 2);
GamePrint.Message("Computer chose: " + computerNumber);

// Add the two numbers.
int sum = playerNumber + computerNumber;
GamePrint.Message("Sum is: " + sum);

// Check if the sum is odd or even.
bool sumIsEvens = sum % 2 == 0;

// Decide the round winner.
bool playerIsEvens = playerSide == 2;
if (playerIsEvens == sumIsEvens)
{
    GamePrint.Success("You win this round!");
}
else
{
    GamePrint.Error("Computer wins this round!");
}

Each player chooses a number, we do the calculations and declare the round winner.

Now, we need to repeat this, until one of the players wins two rounds.

Here we have two different questions to deal with:

  1. Track how many rounds a player wins.
  2. Play consecutive rounds until one of them wins at least two times.

Before dealing with each step, let’s demarcate the round code so it’s easier to identify it.

✅ What to Do

🙈 Solution
Tried, you must, before reveal the solution you may. - Yoda

✏️ Program.cs - Changes

++  // Round starts here.

    // Player enters a number between 1 and 2.
    GamePrint.Input("Choose a number between 1 and 2");
    int playerNumber = GameInput.Number(1, 2);

    GamePrint.Message("You chose: " + playerNumber);

    // Computer randomly generates a number between 1 and 2.
    int computerNumber = GameRandom.Number(1, 2);
    GamePrint.Message("Computer chose: " + computerNumber);

    // Add the two numbers.
    int sum = playerNumber + computerNumber;
    GamePrint.Message("Sum is: " + sum);

    // Check if the sum is odd or even.
    bool sumIsEvens = sum % 2 == 0;

    // Decide the round winner.
    bool playerIsEvens = playerSide == 2;
    if (playerIsEvens == sumIsEvens)
    {
        GamePrint.Success("You win this round!");
    }
    else
    {
        GamePrint.Error("Computer wins this round!");
    }

++  // Round ends here.

🗒️ Program.cs - Final

(...)

// Round starts here.

// Player enters a number between 1 and 2.
GamePrint.Input("Choose a number between 1 and 2");
int playerNumber = GameInput.Number(1, 2);

GamePrint.Message("You chose: " + playerNumber);

// Computer randomly generates a number between 1 and 2.
int computerNumber = GameRandom.Number(1, 2);
GamePrint.Message("Computer chose: " + computerNumber);

// Add the two numbers.
int sum = playerNumber + computerNumber;
GamePrint.Message("Sum is: " + sum);

// Check if the sum is odd or even.
bool sumIsEvens = sum % 2 == 0;

// Decide the round winner.
bool playerIsEvens = playerSide == 2;
if (playerIsEvens == sumIsEvens)
{
    GamePrint.Success("You win this round!");
}
else
{
    GamePrint.Error("Computer wins this round!");
}

// Round ends here.
