Classes and Objects Overview

What is a Class?

A class can be thought of as a blueprint for creating something. It defines the structure and behavior of what you are going to create, which in programming terms is called an object.

cake


              1234567891011
            
class Cake {
public:
    // Attributes
    float flour;
    std::string filling;

    // Methods
    void bake() {
        // working with attributes
    }
};

Attributes: also known as data members, these are the properties that define the state.
Methods: also known as function members, these are the functions or actions that can be performed.

What is an Object?

An object is an instance of a class. When a class is defined, no memory is allocated until an instance of it is created. An object represents a specific example or instance of a class, with actual values assigned to its attributes.

Relationship Between Classes and Objects

Objects are created from a class and each object has its own identity, state, and behavior. Classes and objects have a fundamental relationship where:

Classes define the structure and capabilities.
Objects are specific instances that embody the class definition.

main


              123456789101112
            
int main()
{
    // Creating an object of the Cake class
    Cake myCake;

    // Setting attributes
    myCake.flour = 25.1f;
    myCake.filling = "strawberry";

    // Calling a method
    myCake.bake();
}
