C Sharp (C#) - Properties and Encapsulation

Find the error in this code:

class Product {
  public int Quantity { get; set; }
}

var p = new Product();
p.Quantity = -5;
Console.WriteLine(p.Quantity);

ANo error, code runs and prints -5

BQuantity property missing get accessor

CQuantity property must be readonly

DNegative value assigned without validation

Step-by-Step Solution

Solution:

Step 1: Check property and assignment
Quantity is an int property with get and set accessors.
Step 2: Identify logical error
Assigning -5 may be invalid logically but compiles fine; no validation is present.
Final Answer:
Negative value assigned without validation -> Option D
Quick Check:
Auto-properties don't validate values automatically [OK]

Quick Trick: Add validation to setters to prevent invalid values [OK]
