Introduction
C++ is the most used and most popular programming language developed by Bjarne Stroustrup. C++ is a high-level and object-oriented programming language. This language allows developers to write clean and efficient code for large applications and software development, game development, and operating system programming. It is an expansion of the C programming language to include Object Oriented Programming(OOPs) and is used to develop programs for computers. This C++ Tutorial will cover all the basic to advanced topics of C++ like C++ basics, C++ functions, C++ classes, OOPs and STL concepts.
What is C++?
C++ is a most popular cross-platform programming language which is used to create high-performance applications and software like OS, Games, E-commerce software, etc. It was developed by Bjarne Stroustrup, as an extension of C Programming language . C++ give a high level of control over system resources and memory.
Why Learn C++?
- C++ is one of the most used and popular programming languages.
- C++ is used in making operating systems, embedded systems, and Graphical User Interfaces.
- It is an object-oriented programming language that implements all the OOPs concepts such as Abstraction,
- Encapsulation, and Inheritance, which gives a clear structure to programs and allows code to be reused,
- lowering development costs and providing security.
- It is portable and can be used to create applications that can be adapted to multiple platforms.
- C++ is easy to learn so that you can choose it as your first programming language.
- It makes programming easy for programmers to switch to C++ because its syntax is similar to C, Java, and C#.
Hello World using C++
Just to give you a little excitement about C++ programming, I’m going to give you a small conventional C++ Hello World program, You can try it using Demo link
C++ is a super set of C programming with additional implementation of object-oriented concepts.
#include <iostream>
using namespace std;
// main() is where program execution begins.
int main() {
cout << “Hello World”; // prints Hello World
return 0;
}
There are many C++ compilers available which you can use to compile and run above mentioned program:
- Apple C++. Xcode
- Bloodshed Dev-C++
- Clang C++
- Cygwin (GNU C++)
- Mentor Graphics
- MINGW – “Minimalist GNU for Windows”
- GNU CC source
- IBM C++
- Intel C++
- Microsoft Visual C++
- Oracle C++
- HP C++
Applications of C++ Programming
As mentioned before, C++ is one of the most widely used programming languages. It has it’s presence in almost every area of software development. I’m going to list few of them here:
- Application Software Development – C++ programming course 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 friends of scientists because of 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 development of gaming engines.
- Embedded System – C++ is being heavily used in developing Medical and Engineering Applications like softwares for MRI machines, high-end CAD/CAM systems etc.
Applications of C++
1. Operating Systems
C++ is most widely used programming language and become an ideal choice for developing operating systems. Mac OS X has majority of parts written in C++ and Most of Microsoft’s software like Windows, Microsoft Office, IDE Visual Studio, and Internet Explorer are also written in C++.
2. Games
C++ used for game development and companies use it as their first choice to develop gaming systems because C++ is very close to the machine so It can easily manipulate resources and able to built complex 3D games, multiplayer game, etc. Unreal game engine make games using C++.
3. Web Browsers
Most of the browsers in Computers are developed in C++ for effecting goals and Mozilla Firefox is totally developed by C++ and Google Applications and software like Chrome and Google File System are partly written in C++.
4. Compilers
Compilers of many programming languages are designed in C and C++ and this is because they are moderately lower-level when compared to other higher-level programming languages and C/C++ are closer to the hardware.
5. Embedded Systems
Embedded systems that need the program closer to the hardware such as smartwatches, medical equipment systems, mobile phones etc., are developed in C++ and It can perform a lot of low-level function calls, unlike different high-level programming languages.
