What are constructors in C++ and how do they work?

Can you explain what constructors are in C++?

Sure! Constructors are special member functions in C++ that are called when an object of a class is created. They initialize the object's attributes.

How do you define a constructor in a class?

You define a constructor by creating a function with the same name as the class and no return type. For example, ClassName() { }.

What is the difference between a default constructor and a parameterized constructor?

A default constructor takes no arguments, while a parameterized constructor takes parameters to initialize an object with specific values.

Can you give me an example of a parameterized constructor?

Certainly! Here's an example: ClassName(int x) { this->x = x; } initializes the member variable x with the value passed to the constructor.
