What is the primary purpose of a constructor in a class?

The primary purpose of a constructor in a class is to initialize new objects of that class. When a class is instantiated, the constructor is called automatically to set initial values for its attributes or perform any setup necessary for the object to be in a valid state. This is crucial because it ensures that an object starts its life in a consistent and usable condition, with necessary resources allocated and set up.

Unlike limited access to class members, defining attributes, or destroying objects, the constructor focuses specifically on preparation during the creation of an instance. This initial setup phase is foundational to object-oriented programming, allowing for a structured and predictable way to manage and utilize objects throughout their lifecycle.
