Blueprints

Classes & Objects

A class is a user-defined data type that acts as a blueprint for objects. An object is a real-world instance of a class.

CLASS DEFINITION

class Car {
public:
    string brand;
    void honk() {
        cout << "Beep!";
    }
};

Car myCar; // Object creation
myCar.brand = "Tesla";
myCar.honk();

MEMBERS

Variables inside a class are called "Data Members". Functions are "Member Functions".

INSTANTIATION

The process of creating an object from a class blueprint.

DOT OPERATOR

Use the . operator to access public members of an object. If you have a pointer to an object, use the arrow -> operator.
