Prerequisites

This activity requires you to create code in Visual Studio. You can use the C# Console Application template to complete the exercises in this activity. Enter your code within the Main method of the template and press Ctrl + F5 to run the program without debugging.

Instructions

In this activity, you'll use C# to create basic app logic for the basketball game. Each exercise reflects logic that could be used in a script for game play.

Create a player variable for the app's player and assign your name to the variable.
```
string player = "Gustavo";
```
The player must have possession of the basketball to take a shot. If the player does not have the basketball, then they must wait to take another shot. When the game starts, the player has possession of the basketball up until they shoot the basketball. Create a conditional statement that outputs a string that indicates whether the player can or cannot take a shot.
```
bool hasPossession = true;

if (hasPossession == true)
{
    Console.WriteLine("Player can take the shot.");
}
else
{
    Console.Write("Player cannot take the shot.");
}
```
Create a score variable for the total number of points received from a successful basketball shot.
```
int score;
```
When the game starts, the score is set to 0. Each time the player makes a successful shot, their score increases by 1 point. Create a TakeShot method that increments the player's score by 1 point if their shot is successful.
```
static void TakeShot()
{
    int score = 0;
    bool shotSuccessful = false;

    if (shotSuccessful == true)
    {
        score++;
    }
}
```
The player has 5 chances to make a shot. After their 5th shot, the game is over. Create a while loop that executes the TakeShot method until the player has taken their 5th shot.
```
int numShots = 5;

while (numShots > 0)
{
    TakeShot();
}
```
When the game is over, the total score is output for the player. Use the Console.WriteLog() command to create a string that outputs the player's name and score.
```
Console.WriteLine(player + " has scored " + score + " points!");
```

Bonus

Without a game in play, it can be a challenge to verify whether the program you created is valid. However, there's a way to programmatically simulate game play! The ConsoleReadLine() command accepts input and stores the value to a variable within the program. Once the value is stored, the program can use the value as it continues to execute the script.

Using ConsoleReadLine(), modify the program you created to simulate game play. Use ConsoleReadLine() to do the following:

Ask and assign the player's name to the player value. Welcome the player and inform them that the game is about to start.
Confirm whether the player's shot was successful. If the player makes the shot, then increase their score by 1 point. If the player doesn't make the shot, then tell the player to try again.
Once game is over, print the player's final score to the console.

    static void Main(string[] args)
    {
        Console.WriteLine("What is your name?: ");

        string player = Console.ReadLine();

        Console.WriteLine("Welcome " + player + "! The game starts in 3...2...1..Go!");

        TakeShot();
    }

    static void TakeShot()
    {
        int numShots = 5;
        int score = 0;

        while (numShots > 0)
        {
            Console.WriteLine("Did you make the shot? (Y/N) ");
            string shotResponse = Console.ReadLine();

            if (shotResponse == "Y")
            {
                score++;
                numShots--;
            }
            else
            {
                numShots--;
                Console.WriteLine("Try again.");
            }

        }
        
        Console.WriteLine("Game Over! You scored " + score + " points!");
    }
}
