C++ Environment Setup

Local Environment Setup
If you’re still willing to set up your environment for C++, you need to have the following two soft wares on your computer.
Text Editor


This will be used to types your program. Example of few editors includes Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim or vi.
Name and version of text editor can vary on the different operating system. For examples, 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 extensions .cpp, .cp, or .c.
The text editor should be in place to start your C++ programming.

C++ Compiler
This’s an actual C++ compiler, which will be used to compile your source code into the final executable program.
Most C++ compilers do not care what extension you give to your source code, but if you do not specify otherwise, many will use .cpp by default.
Most frequently used and free available compiler’s GNU C/C++ compiler, otherwise you can have compilers either from HP or Solaris if you’ve got the respective Operating Systems.
Installing GNU C/C++ Compiler
UNIX/Linux Installation
If you’re 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 that  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 isn’t installed, then you will have to install it yourself using the detailed instructions available at https://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 environments 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 in Windows you need to install MinGW. To install MinGW, when you go to the MinGW homepage, and follows the link to the MinGW download page. Download the latest version of the MinGW installation programs which should be named MinGW-<version>.exe.
While installing MinGW, at the 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 installations to your PATH environments variable, so that you can specify these tools on the command lines by their simple names.
When the installation is complete that you will be able to run gcc, g++, ar, ranlib, dlltool, and severally other GNU tools from the Windows command line.
