class Score {
  private $points = 0;
  public function addPoint() {
    $this->points++;
  }
  public function getPoints() {
    return $this->points;
  }
}

C1

DError

Step-by-Step Solution

Solution:

Step 1: Analyze the class
The class Score has a private property $points initialized to 0.
Step 2: Method calls
Each call to addPoint() increments $points by 1.
Step 3: Counting increments
Three calls to addPoint() increase $points from 0 to 3.
Step 4: Output
getPoints() returns 3, which is echoed.
Final Answer:
3 -> Option A
Quick Check:
Increment thrice, output is 3 [OK]

Quick Trick: Increment private property via $this-> [OK]

Common Mistakes:

Confusing private property access
Expecting error due to private visibility
