What is the function of a constructor in a class?

• A. To delete objects from memory
• B. To initialize new objects of the class
• C. To define static methods within the class
• D. To create subclasses

Answer: (B)

The function of a constructor in a class is to initialize new objects of that class. When an object is created, the constructor is automatically called to set up the initial state of the object. This often involves assigning values to instance variables, allocating resources, or performing any setup required for the object to function correctly.

For example, if a class represents a car, the constructor might initialize properties such as the car's color, model, and year. By doing so, every time an instance of that car class is created, it will have its own specific attributes set up immediately through the constructor, ensuring that the object is in a valid state from the moment it is instantiated.

This is crucial in object-oriented programming, as it allows for the encapsulation of data and behavior in a single entity, making the code more organized and easier to maintain.
