The document discusses object oriented programming and inheritance. It defines object oriented programming as creating objects that contain both data and methods. It describes some advantages of OOP over procedural programming, including being faster and easier to execute. It explains that classes are templates for objects, and that objects are instances of classes. The document provides an example of creating a Car class with a color variable, and creating an object from the class to print the color value. It also mentions inheritance will be discussed.

3. AGENDA
• Object Oriented Programming
• Inheritance

4. OBJECT ORIENTED PROGRAMMING

5. OBJECT ORIENTED PROGRAMMING (OOP)
• OOP stands for Object-Oriented Programming
• Procedural vs OOP
• Procedural programming is about writing procedures or methods that perform operations on the data
• Object-oriented programming is about creating objects that contain both data and methods.
• Object-oriented programming has several advantages over procedural programming:
• OOP is faster and easier to execute
• OOP provides a clear structure for the programs
• OOP helps to keep the C# code DRY "Don't Repeat Yourself", and makes the code easier to maintain,
modify and debug
• OOP makes it possible to create full reusable applications with less code and shorter development time

6. CLASSES AND OBJECTS ARE THE TWO MAIN
ASPECTS OF OBJECT-ORIENTED PROGRAMMING.
• a class is a template for objects
• an object is an instance of a class
• When the individual objects are created, they inherit all the variables and
methods from the class

8. CREATING A CLASS
• Create a class named "Car" with a variable color:
class Car
{
string color = "red";
}

9. CREATE AN OBJECT
• Create an object called "myObj" and use it to print the value of color:
class Car
{
string color = "red";
static void Main(string[] args)
{
Car myObj = new Car();
Console.WriteLine(myObj.color);
}
}

10. CLASS MEMEBERS
• Fields and methods inside classes are often referred to as "Class Members":

16. DISCUSSION
• Why is this important?
• How can this be useful to me?
• How can I use this in my current
job?
• How can I use this in my future
career?
• What will I get out of this?
• How is this used in the real world
