Identify the error in this C# class that tries to track a score:

class Game {
  int score;
  public void AddPoints(int points) {
    score = score + points;
  }
  public int GetScore() {
    return score;
  }
}

var g = new Game();
g.AddPoints(5);
Console.WriteLine(g.GetScore());

ANo error; code runs and prints 5

Bscore should be declared static

CAddPoints method should return int

Dscore is not initialized and may have a default value

Step-by-Step Solution

Solution:

Step 1: Check field initialization rules in C#
Instance fields like score default to 0 if not explicitly initialized.
Step 2: Verify method behavior and output
AddPoints adds points correctly, and GetScore returns the updated score. The code prints 5 as expected.
Final Answer:
No error; code runs and prints 5 -> Option A
Quick Check:
Uninitialized int defaults to 0 in C# [OK]

Quick Trick: Instance int fields default to 0 if not set [OK]

Common Mistakes:

MISTAKES

Thinking uninitialized int fields cause errors
Believing AddPoints must return a value
Confusing static and instance fields
