In these C++ tutorials, we are going to learn the C++ programming language. First of all, I am going to explain how these C++ tutorials will differ from other sources of learning C++:
Here is the content outline which we are going to cover in today's C++ tutorial:
Before starting this C++ tutorial, we should know the reason behind learning a programming language? Let me answer this fundamental question for you. A programming language helps a user to communicate with the computer properly. For example, if a person wants to talk to another person, he must learn a language (like English, Hindi, Bangla, etc.), which another person can understand. If a human wants to talk to the computer or give some instructions, he has to learn a language which computers can understand. There are many languages that computers can understand, like python, java, and C++.
As we are going to learn C++ in this set of tutorials - here arises another essential question: why learn C++ despite it being an ancient programming language? Bjarne Stroustrup developed C++ as an addition to C language. The main reason to use C++ is that it is very close to the hardware, which means that it is beneficial for the programmer to give direct instructions to a device without using any intermediate medium. Another reason to use C++ is that it is an object-oriented programming language, and object-oriented languages can create complex real-world software systems. Well, we will dive very deep into OOPs and inheritance later in this course!
Visual studio is a source code editor - free to use, provided & maintained by Microsoft. Below is the process of downloading and installing visual studio code:
Step 1: Go to Google and search "VS Code install" and click on the Visual studio link as shown in the image below
