Initialization

Constructors

A special member function that is automatically called when an object of a class is created. Its main job is to initialize the object's data members.

TYPES OF CONSTRUCTORS

Default Constructor: Takes no arguments.
Parameterized Constructor: Takes arguments to initialize members with specific values.
Copy Constructor: Creates a new object as a copy of an existing one.

Code Example

class Point {
public:
    int x, y;
    // Parameterized Constructor
    Point(int x1, int y1) {
        x = x1; y = y1;
    }
};

Point p(10, 20);

IMPORTANT RULES

Constructors have the SAME name as the class. They have NO return type (not even void). They are usually public.
