Try it Option Online
You really do not need to set up your own environment
to start learning C++ programming language. Reason is very simple, we have
already set up C++ Programming environment online, so that you can compile and
execute all the available examples online at the same time when you are doing
your theory
work. This gives you confidence in what you are reading
and to check the result with different options. Feel free to modify any example
and execute it online. Try the following example using our online compiler
option available at
For most
of the examples given in this tutorial, you will find Try it option in
our website code sections at the top right corner that will take you to the
online compiler. So just make use of it and enjoy your learning.
Local Environment Setup
If you are
still willing to set up your environment for C++, you need to have the following
two softwares on your computer.
Text Editor:
This will
be used to type your program. Examples of few editors include Windows Notepad,
OS Edit command, Brief, Epsilon, EMACS, and vim or vi.
Name and version of text editor can vary on different operating systems. For example, Notepad will be used on Windows and vim or vi can be used on windows as well as Linux, or UNIX.
The files you create with your editor are called source files and for C++ they typically are named with the extension .cpp, .cp, or .c.
A text
editor should be in place to start your C++ programming.
C++ Compiler:
This is an
actual C++ compiler, which will be used to compile your source code into final
executable program.
Most C++
compilers don't care what extension you give to your source code, but if you
don't specify otherwise, many will use .cpp by default.
Most
frequently used and free available compiler is GNU C/C++ compiler, otherwise
you can have compilers either from HP or Solaris if you have the respective
Operating Systems.
Installing GNU C/C++ Compiler:
UNIX/Linux Installation:
If you are
using Linux or UNIX then check whether GCC is installed on your system
by entering the following command from the command line:
$
g++ -v
If you
have installed GCC, then it should print a message such as the following:
Using
built-in specs.
Target:
i386-redhat-linux
Configured
with: ../configure --prefix=/usr .......
Thread
model: posix
gcc
version 4.1.2 20080704 (Red Hat 4.1.2-46)
If GCC is
not installed, then you will have to install it yourself using the detailed instructions
available at http://gcc.gnu.org/install/ .
Mac OS X Installation:
If you use
Mac OS X, the easiest way to obtain GCC is to download the Xcode development
environment from Apple's website and follow the simple installation instructions.
Xcode is
currently available at developer.apple.com/technologies/tools/.
Windows Installation:
To install
GCC at Windows you need to install MinGW. To install MinGW, go to the MinGW
homepage, www.mingw.org, and follow the link to the MinGW download page.
Download the latest version of the MinGW installation program which should be
named MinGW-<version>.exe.
While
installing MinGW, at a minimum, you must install gcc-core, gcc-g++, binutils,
and the MinGW runtime, but you may wish to install more.
Add the
bin subdirectory of your MinGW installation to your PATH environment variable
so that you can specify these tools on the command line by their simple names.
When the
installation is complete, you will be able to run gcc, g++, ar, ranlib, dlltool,
and several other GNU tools from the Windows command line.
