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

There are many text editors and compilers to choose from. In this tutorial, we will use an IDE (see below).

-----------------------------------------------------------------------------------

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 Code blocks at http://www.codeblocks.org/. 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;bA

}

-----------------------------------------------------------------------------------

Don't worry if you don't understand the code above - we will discuss it in detail in later chapters. For now, focus on how to run the code.

In Codeblocks, it should look like this:
