LESSON 279 OF 667 · FUNCTIONS & CLASSES

Member Functions in C++

Lesson

TL ; DR:

A member function (or method) is a function declared inside a class. It can read and write the object's data members.

Define member functions under public: so they can be called from outside:

class Dog {
public:
    string name;
    Dog(string name) { this->name = name; }

    void bark() {
        cout << "Woof! I am " << name << endl;
    }
};

Call it on an object with the dot operator: dog.bark();

Full lesson:

So far you've added data to a class with member variables and a constructor. The other half of OOP is behavior — actions an object can perform. That's what member functions are for.

Your task

Add a bark() member function that prints "Woof! I am " followed by the dog's name.

Woof! I am Rex
