Arrow Operator (->) with Pointers:
- When you have a pointer to an object, you use the arrow operator to access data members and call member functions.
- The syntax is pointer->memberName to access data members or call member functions.

Example with pointers:

In this example, `ptr` is a pointer to a `MyClass` object. The arrow operator allows us to access the object’s data members and call its member functions using the pointer.

Using the correct operator (dot or arrow) is essential depending on whether you are working with an object or a pointer to an object. The dot operator is used with objects, and the arrow operator is used with pointers to objects.

In this example, the `Person` class has a constructor that takes two parameters (`newName` and `newAge`) to initialize the `name` and `age` data members of the object. When you create an object using the constructor, it automatically sets the provided values for the data members.

Constructors play a crucial role in ensuring that objects are properly initialized and ready for use, making them an essential aspect of object-oriented programming in C++.

In this example, the `Rectangle` class has a parameterized constructor that takes two arguments (`initialWidth` and `initialHeight`) to initialize the `width` and `height` data members of the object `myRectangle`.

Constructors play a crucial role in setting up the initial state of objects, making them an essential aspect of object-oriented programming in C++.

In this example, we define a `Student` class with private data members (`name`, `age`, and `rollNumber`) and public member functions (`setName`, `setAge`, `setRollNumber`, `getName`, `getAge`, and `getRollNumber`). We also have a constructor to initialize the data members when an object is created.

The `main` function demonstrates how to create an object of the `Student` class, set and retrieve its data members using the member functions, and modify the age using the `setAge` member function.

When you run this program, it will output:

This shows the basic structure of a class in C++, its data members, member functions, and how to work with objects of the class to manipulate and access its properties.
