OBJECT ORIENTED PROGRAMMING UNIT; Object-oriented programming unit is a programming paradigm based on the concept of “objects”, which can contain data and code: data in the form of fields, and code, in the form of procedures. A feature of objects is that an object’s own procedures can access and often modify the data fields of itself.

OBJECT ORIENTED PROGRAMMING TOPICS COVERED

Introduction to object oriented programming
Control structures and functions
Objects classes and inheritance
Polymorphism
Input/output and file management

Introduction to object oriented programming

This topic trainees will be able to learn; OOP introduction As the name suggests, Object-Oriented Programming or OOPs refers to languages that use objects in programming. Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism, etc in programming

Control structures and functions

This topic trainees will be able to learn; control structure which is like a block of programming that analyses variables and chooses a direction in which to go based on given parameters. The term flow control details the direction the program takes (which way program control “flows”). Hence it is the basic decision-making process in computing; There are 3 main control structures learned in object oriented programming: Sequence, Selection and Repetition.

Objects classes and inheritance

This topic trainees will be able to learn; Inheritance in object-oriented programming which is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation. An inherited class in OOP is called a subclass of its parent class or super class. Classes in OOP are user-defined data types that act as the blueprint for individual objects, attributes and methods. Objects are instances of a class created with specifically defined data. Objects can correspond to real-world objects or an abstract entity.

Polymorphism

This topic trainees will be able to learn; Polymorphism which is one of the core concepts of object-oriented programming (OOP) and describes situations in which something occurs in several different forms. In computer science, it describes the concept that you can access objects of different types through the same interface

Input/output and file management

This topic trainees will be able to learn; File handling which provides a mechanism to store the output of a program in a file and to perform various operations on it. A stream in file management is an abstraction that represents a device on which operations of input and output are performed. The set of file handling methods learned include ifstream, ofstream, and fstream.
