Classes and Objects

In C++, classes are used to define objects. A class is a blueprint that defines the properties and behaviors that an object of that class will have.

To define a class in C++, you can use the class keyword followed by the name of the class.

1// Class definition
2
3class Car {
4    // Class members
5};

The class can have attributes (properties) and methods (functions).

1// Class definition
2
3class Car {
4    // Attributes
5    string brand;
6    int year;
7
8    // Methods
9    void start() {
10        cout << "Starting the car" << endl;
11    }
12};

To create an object of a class, you can use the class name followed by the object name and optional parentheses.

1// Create an object of the Car class
2class Car myCar;

Once you have created an object, you can access its attributes and call its methods using the dot operator.

1// Access the attributes and methods of the object
2myCar.brand = "Toyota";
3myCar.year = 2020;
4
5myCar.start();
