📘 C# Classes and Objects Practice

This project demonstrates the fundamental and intermediate concepts of Object-Oriented Programming (OOP) in C#. It covers creating classes, defining fields, using constructors, initializing objects, applying methods, and implementing method overloading.

🧠 Concepts Covered

• Creating Classes and Objects
• Object Initialization (two methods)
• Using Fields and Methods
• Working with Lists of Objects
• Constructors and Parameterized Constructors
• Method Overloading
• Combining Classes with Loops and Conditions

🧩 Task Overview

1. Creating a Simple Class (Person Class)

✅ Goal: Understand how to define a class with properties and initialize an object using both:

• Default constructor + property assignment.
• Object initializer syntax.

2. Bottle Class Example

✅ Goal: Learn to create simple classes with properties and display object data.

3. Class with a Method (Calculator Class)

✅ Goal: Understand how to define and call methods inside a class.

4. List of Objects (Mobile Class Example)

✅ Goal: Practice creating and iterating over a list of custom objects.

🏗️ Constructors

5. Parameterized Constructor (Toyota Class)

✅ Goal: Learn to use constructors for initializing class data.

6. Creating List of Objects Using Constructor (Student Class)

✅ Goal: Learn to instantiate multiple objects dynamically using constructors.

7. Product List with Constructor

✅ Goal: Practice constructors with multiple parameters and lists.

8. Student Marks Average Calculator

✅ Goal: Combine constructors and methods for data calculation.

9. Employee Salary Calculator

✅ Goal: Demonstrate class methods and business logic inside constructors.

🔄 Method Overloading

10. Suzuki Car Example

✅ Goal: Learn how method and constructor overloading allow multiple ways to create objects.

🧾 Summary

Concept	Description
Class	Blueprint for creating objects.
Object	Instance of a class containing real data.
Constructor	Initializes an object’s data when created.
Method	Performs an action using object data.
Overloading	Multiple constructors or methods with different parameters.
List of Objects	Used to manage multiple instances efficiently.

🏁 Conclusion

Through these exercises, you’ve practiced:

• Declaring and using classes and objects.
• Creating constructors and understanding their purpose.
• Working with lists of custom objects.
• Using methods and method overloading effectively.

These tasks form the foundation of Object-Oriented Programming (OOP) in C# and are essential for building scalable applications.
