Project

Object-oriented programming (OOP) has been around for decades. As the original object-oriented language, C# is a mainstay in the world of computer programming.

All the concepts of object-oriented programming that C# developers love to have in their arsenal are explained in detail along with relevant coding examples and exercises in this course.

This course is unique in its nature as it follows a project-based learning approach. Throughout the course, a real-world example of vending machine is followed to help the learners develop a firm understanding of the stated OOP concepts.

The learners will not only be able to play around with the project,  they’ll also be able to see all the concepts in action in this project.

# Problem Statement

Implement a class, `Student`, that has four fields with properties and two methods. This challenge is designed to test your understanding of following good OOP practices. The problem can be broken down into three tasks:


## Task 1
* The properties should only have the `get` block defined for the relative fields, you can skip the `set` block.
* Implement a parameterized constructor to initialize the values of four properties: `Name`, `PhysicsMarks`, `ChemistryMarks`, and, `BioMarks`.


## Task 2
Implement a method, `TotalObtained()`, in the `Student` class that calculates and returns the total marks of a student.


## Task 3
Using the `TotalObtained()` method, implement another method, `Percentage()`, in the `Student` class that calculates the percentage of the student's marks. Assume that the total marks of each subject are **100**. So, the combined marks of three subjects are **300**.

Below is the formula for calculating the percentage:

## Sample Input
```c#
Student john = new Student("John", 75, 75, 90)
```
## Sample Output
```c#
john.TotalObtained() = 240
john.Percentage() = 80
john.PhysicsMarks = 75

In this exercise, you have to analyze a student's performance using the concept of classes
