C++ Introduction

What is C++?

C++ is a cross-platform language that can be used to create high-performance applications. It was developed by Bjarne Stroustrup at Bell Labs in 1979, as an extension to the C language.

C++ gives programmers a high level of control over system resources and memory. It 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 language that gives a clear structure to programs and allows code to be reused, lowering development costs. It is portable and can be used to develop applications that can be adapted to multiple platforms.


C++ Get Started

To start using C++, you need two things:

  • A text editor, like Notepad, to write C++ code
  • A compiler, like GCC, to translate the C++ code into a language that the computer will understand

C++ Install IDE

An IDE (Integrated Development Environment) is used to edit AND compile the code.

Popular IDE's include Code::Blocks, Eclipse, and Visual Studio. These are all free, and they can be used to both edit and debug C++ code.

Note: Web-based IDE's can work as well, but functionality is limited.

We will use Code::Blocks in our tutorial, which we believe is a good place to start.

You can find the latest version of Codeblocks at https://www.codeblocks.org/downloads/26. Download the mingw-setup.exe file, which will install the text editor with a compiler.


C++ Quickstart

Let's create our first C++ file.

Open Codeblocks and go to File > New > Empty File.

Write the following C++ code and save the file as myfirstprogram.cpp (File > Save File as): myfirstprogram.cpp



#include <iostream>
using namespace std;

int main() {
  cout << "Hello World!";
  return 0;

In Codeblocks, it should look like this:


Then, go to Build > Build and Run to run (execute) the program. The result will look something to this:

Hello World!
Process returned 0 (0x0) execution time : 0.011 s
Press any key to continue.

Congratulations! You have now written and executed your first C++ program.
