Going deeper into class

When we declare a class, we need to start defining by class.

Class members can be of three types:

• Public

• Private

• Protected

Don't worry about these classifications for now. We will get into the types later.

Let's look at an example first.

A box has three dimensions-length, width, and height. We can define the Box class as follows:

class Box{ 
double lengthOfBox; 
double heightOfBox; 
double widthOfBox;  
} 

lengthOfBox, heightOfBox, and widthOfBox are the members of the Box class. If we want to make the class Public, Private, or Protected, we can declare them as follows:

class Box1 { 
  Public: 
    double lengthOfBox1; 
    double heightOfBox1; 
    double widthOfBox1; 
}; 
 
class Box2 { 
  Private: 
    double lengthOfBox2; 
    double heightOfBox2; 
    double widthOfBox2; 
}; 
 
class Box3 { 
  Protected: 
    double lengthOfBox3; 
    double heightOfBox3; 
...
