C++ Programming Tutorial

Introduction to Object-Oriented Programming

• Introduction to programming language and software evaluation
• Difference between Object-Oriented Programming (OOP) and Procedure-Oriented Programming (POP)
• Basic concepts of memory, operators, and control structures
• Introduction to IDEs such as Dev-C++ and Visual Studio

Importance of Object-Oriented Programming

• Faster and easier to execute
• Provides a clear structure for programs
• Helps to keep code DRY (Don't Repeat Yourself)
• Makes code easier to maintain, modify, and debug
• Enables creation of full reusable applications with less code and shorter development time

Object and Class

• Objects are entities in a software system that represent instances of real-world and system entities
• Objects have two main properties: State (attributes) and Behavior (methods)
• Examples of objects: Computer, Pen, Car, Book, Apple, Cat, Bank Account, Results

Class

• A Class is a blueprint of an object
• A Class describes the object
• A Class is a general, abstract representation of an object that specifies the fields and methods that such an object has

Class and Object Example

• Class Car example: Properties (Company, Model, Color, Mfg.year, Price, Mileage) and Methods (Start, Drive, Park)
• Constructing Objects from Classes: Once a class has been defined, it can be used to create any number of objects of that class

Simple Class Declaration

• A typical class declaration: class Item { int number; float cost; public: int getdata(int a, float b); void putdata(void); };
