Object-oriented programming (OOP) has been around for decades. If you have a basic understanding of C++ and are interested in leveling up your skills, this class will help you do just that. 

Starting with an overview of the basics, you’ll dive into understanding the time-honored technique for implementing complex applications using user-defined classes. Followed up by discussing classes and objects, and then building up to the high-level topics including inheritance and polymorphism. 

Throughout the course, you’ll be fully immersed in OOP for C++, with illustrations, exercises, quizzes, and hands-on challenges every step of the way. You’ll walk away with an understanding of classes and objects behavior and be able to easily create simple, efficient, reusable and secure code.

# Problem Statement

Write a C++ **class** called `Calculator` with 

* `private` *member variables*: 

  * `num1` and `num2` (**float** type)

And *member functions*:

* `add(float n1, float n2)`, a *function* which returns the addition of two numbers

* `Subtract(float n1, float n2)`, a *function* which returns the subtraction of n1 from n2
 
* `multiply(float n1, float n2)`, a *function* which returns the multiplication of numbers

* `divide(float n1, float n2)`, a *function* which returns the division of n2 by n1

* Define a default constructor which initializes both numbers by **zeros**

## Input
Pass floating point numbers in the member functions

## Output
Addition, Subtraction, division, and multiplication
## Sample Input
``` C++
calculator obj;
obj.add(10, 94)
obj.subtract(10, 94)
obj.multiply(10, 94)
obj.divide(10, 94)
```
## Sample output
``` C++
104
84
940
9.4
```

In this exercise, you have to implement a calculator which can perform addition, subtraction, multiplication, and division.
