C++ Introduction

C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979  at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This C++ tutorial adopts a simple and practical approach to describe the concepts of C++ for beginners to advanded software engineers.

What is C++?

  • C++ is a cross-platform language that can be used to create high-performance applications.
  • C++ was developed by Bjarne Stroustrup, as an extension to the C language.
  • C++ gives programmers a high level of control over system resources and memory.
  • The language was updated 4 major times in 2011, 2014, 2017, and 2020 to C++11, C++14, C++17, C++20.
Why Learn C++

C++ is a MUST for students and working professionals to become a great Software Engineer. I will list down some of the key advantages of learning C++:

  • C++ is one of the world's most popular programming languages.
  • C++ can be found in today's operating systems, Graphical User Interfaces, and embedded systems.
  • C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs.
  • C++ is portable and can be used to develop applications that can be adapted to multiple platforms.
  • C++ is fun and easy to learn!
  • As C++ is close to C, C# and Java, it makes it easy for programmers to switch to C++ or vice versa.
  • C++ is very close to hardware, so you get a chance to work at a low level which gives you lot of control in terms of memory management, better performance and finally a robust software development.
  • C++ programming gives you a clear understanding about Object Oriented Programming. You will understand low level implementation of polymorphism when you will implement virtual tables and virtual table pointers, or dynamic type identification.
  • C++ is one of the every green programming languages and loved by millions of software developers. If you are a great C++ programmer then you will never sit without work and more importantly you will get highly paid for your work.
  • C++ is the most widely used programming languages in application and system programming. So you can choose your area of interest of software development.
  • C++ really teaches you the difference between compiler, linker and loader, different data types, storage classes, variable types their scopes etc.

Difference between C and C++

  • C++ was developed as an extension of C, and both languages have almost the same syntax.
  • The main difference between C and C++ is that C++ supports classes and objects, while C does not.

Characteristics

Learning C++ 

File Name :- myfirstprogram

Code::- 

  1. #include <iostream>
  2. using namespace std;

  4. int main() {
  5.   cout << "Hello World!";
  6.   return 0;
  7. }

Result::- 

Hello World!

Applications of C++ Programming

As mentioned before, C++ is one of the most widely used programming languages. It has its presence in almost every area of software development. I'm going to list a few of them here:

  • Application Software Development - C++ programming has been used in developing almost all the major Operating Systems like Windows, Mac OSX and Linux. Apart from the operating systems, the core part of many browsers like Mozilla Firefox and Chrome have been written using C++. C++ also has been used in developing the most popular database system called MySQL.
  • Programming Languages Development - C++ has been used extensively in developing new programming languages like C#, Java, JavaScript, Perl, UNIX’s C Shell, PHP and Python, and Verilog etc.
  • Computation Programming - C++ is the best friend of scientists because of its fast speed and computational efficiencies.
  • Games Development - C++ is extremely fast which allows programmers to do procedural programming for CPU-intensive functions and provides greater control over hardware, because of which it has been widely used in the development of gaming engines.
  • Embedded System - C++ is being heavily used in developing Medical and Engineering Applications like software for MRI machines, high-end CAD/CAM systems etc.

Learning C++ Part 2 Example

C++ Functions A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times. Create a Function C++ provides some pre-defined functions, such as main(), which is used to execute code. But you can also create your own functions to perform certain actions. To create (often referred to as declare) a function, specify the name of the function, followed by parentheses (): Syntax void myFunction() {   // code to be executed } Example Explained myFunction() is the name of the function void means that the function does not have a return value. You will learn more about return values later in the next chapter inside the function (the body), add code that defines what the function should do Call a Function Declared functions are not executed immediately. They are "saved for later use", and will be ...
