Ask for Player Number

📖 Instructions#

Now we need the player to pick a number between 1 and 2. This is the same pattern you used to read the player’s choice — print a prompt, read the input, parse it into an integer.

🧠 Recall

Parsing

✅ What to Do#

Ask the player to choose a number between 1 and 2, read their input, and store the parsed result in an integer variable named playerNumber.

🎯 Expected Outcome#

Welcome to Odds and Evens!
Choose 1 for Odds or 2 for Evens:
1
You chose Odds.
Choose a number between 1 and 2:
1

💡 Hints#

Hint 1

You’ve done this before. Look at the lines that handle the player’s choice — the structure is the same.

Hint 2

You need three things: a print statement for the prompt, a line to read the input, and a line to parse it.

Hint 3

The prompt message is Choose a number between 1 and 2:. The variable name is playerNumber.

⚠️ Common Mistakes#

Reusing playerChoice instead of declaring a new variable

playerChoice and playerNumber are two separate values. Declare a new variable for the player’s number — don’t overwrite the choice.

Forgetting to parse the input

Console.ReadLine() always returns a string. If you skip the parse step, playerNumber will be a string instead of an integer and comparisons later will fail.

Using the wrong variable name

The variable must be named playerNumber — it’s referenced by name in the lessons that follow. A different name will cause confusion when the code grows.

🙈 Solution#

Tried, you must, before reveal the solution you may.

Program.csChanges

  // Player enters a number between 1 and 2.
+ Console.WriteLine("Choose a number between 1 and 2:");
+ string rawNumber = Console.ReadLine();
+ int playerNumber = int.Parse(rawNumber);

Program.csFinal

Console.WriteLine("Welcome to Odds and Evens!");

// Player chooses to play with odds or evens.
Console.WriteLine("Choose 1 for Odds or 2 for Evens:");
string input = Console.ReadLine();
int playerChoice = int.Parse(input);

if (playerChoice == 1)
{
    Console.WriteLine("You chose Odds.");
}
else
{
    Console.WriteLine("You chose Evens.");
}

// Player enters a number between 1 and 2.
Console.WriteLine("Choose a number between 1 and 2:");
string rawNumber = Console.ReadLine();
int playerNumber = int.Parse(rawNumber);
