C++ Programming Language
C++ is an object-oriented programming language that follows the concepts of OOP. It
is not purely object-oriented but has some elements of procedural programming.
Theory and Practical Aspects of Programming
This video will demonstrate how to learn the theory and practical aspects of
programming in C++. We have configured the Visual Studio Code compiler and checked
by running a simple program to print "Hello World" on the screen. In this video, we
will discuss both the theoretical concepts and practical aspects of the language.
Object-Oriented Programming
The next video will cover how to use the language, and the first episode will focus
on the theory of object-oriented programs. The series aims to teach object-oriented
programming, and the previous episode provides a guide to the first chapter of this
episode. We have been given access to the latest episode of C++ programming
language.
Procedural Programming Paradigm
Procedural programming is divided into parts that are known as procedures or
functions. Data movement is more, so data is less secure in this case. Procedural
programming paradigms focus on the algorithm, how to do the task rather than the
data, whereas in object-oriented programming, we focus more on the data than how
the task is done.
C programming language is not well suited for large and complex scalable
applications. Scalability is also not there, and security is not a strong point. In
OOP, we have security, and we will discuss how it could be done in later videos.
Creating Software
We are creating software like a hospital management system, library management
system, shopping cart, and some e-commerce websites like Amazon and Flipkart. We
will write a simple program to add two numbers and print "Hello World." We will
also talk about how it is possible to create software that can be used to run a
hospital or a computer in the future.
We will use a virtual machine to run software that has been used in the past. It
will be a virtual reality-based software that would be used for the first time in
the next time. It could be a database that would have a virtual environment, and it
has been designed to be used by a virtual space. We are designed to have a physical
environment, and we would have virtual space or physical space. We need to use
virtual space, and we use software to run programs.
Object Oriented Programming (OOP) vs Processor Oriented Programming (POP)
Processor oriented programming is not suitable for complex and large scale
applications due to data security concerns. This is why we use Object Oriented
Programming. Each object has its own attributes (height, color, weight, etc.) which
we represent as variables, as well as behavior (coding, sleeping, etc.). This
increases productivity and eliminates the need to repeat code.
Classes and objects are the main pillars of OOP. Without them, a program cannot be
written. Inheritance allows for code reusability. OOP is designed to communicate
through message passing and provide secure data for the application user.
The four pillars of OOP are Abstraction, Encapsulation, Inheritance and
Polymorphism.
