C++ Started


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.

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 http://www.codeblocks.org/downloads/26.

Download the mingw-setup.exe file, which will install the text editor with a compiler.


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


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;
}
Result

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:

When learning C++ at robomag.xyz, you can use our "Submit Example" tool, which shows both the code and the result.

This will make it easier for you to understand every part as we move forward:


myfirstprogram.cpp
#include <iostream>
using namespace std;

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