    In C++, a class is a user-defined data type that serves as a blueprint for creating objects. It encapsulates data members (variables) and member functions (methods) that operate on the data. This encapsulation is a fundamental concept in Object-Oriented Programming (OOP), allowing for data abstraction and modularity.

    Defining a Class

    A class is defined using the class keyword followed by the class name and a pair of curly braces containing its members. Here's a basic example:

    class MyClass {
    public:
    int myNum; // Attribute (int variable)
    std::string myString; // Attribute (string variable)

    void print() { // Member function
    std::cout << "Number: " << myNum << ", String: " << myString << std::endl;
    }
    };
    Cóipeáilte!

    In this example, MyClass has two attributes (myNum and myString) and one member function (print). The public keyword is an access specifier that allows members to be accessed from outside the class.

    Creating Objects

    To use the data and functions defined in a class, you need to create objects. An object is an instance of a class. Here's how you can create an object of MyClass and access its members:

    What is class in C++?
    Class is a level higher than the object and represents the category of objects. Thus, class acts as a blueprint that outlines the object design and details. This includes data that is used to describe the object and various methods or functions that can act on the object data. => Watch Out The Simple C++ Training Series Here.
