Attributes of the Class

Class is like a container for two primary elements: attributes and methods. In this chapter we will learn about attributes and how to use them. For a student class common attributes will be name, gpa, email etc.

Understanding Attributes

Attributes, also often referred as properties or fields, they are the variables that are held within a class. Their job is to represent the state or qualities of objects created from the class.

Public attributes and methods in a class can be directly accessed using the dot operator (.) on an object of the class.

cpp

main

copy

              
12345678910

            
class Example {
public:
    float attribute;
};

int main()
{
    Example obj;
    obj.attribute = 25;
}

Note

Don't be bothered about public keyword. It will be explained later.
