What is text editor in C?

You use text editor to type programs. Windows Notepad, EMACS, OS Edit command and vim are 

some text editors. Other text editors include Epsilon, vi and Brief. You must also remember that

 version and name of text editors will be different. Because it will depend on operating system.

You can see that on Windows, you use Notepad. However, on UNIX or Linux, you use either vi or vim.

Source files

source files are those files that you create in your text editor. It is so because these files have program 

source codes. In addition, source files for C programs have ‘.c’ extension.

C compiler

As we explained about source files. We can read these files. But computer will not be able to read 

them. So, compiling these files is necessary. Compilation will change source files language to machine

 language. In this way, CPU will execute program. Moreover, it will only follow instructions.

Programmers use GNU C/C++ compiler to compile programs. As it is ‘free to use compiler’. However,

 you may even use Solaris or HP compiler. To help you further, we discussed in detail installation

 process. This will be helpful to set up C environment language.

Steps to install GCC on UNIX or Linux

You must first check the system. Whether GCC is there or not there. For that you must enter a 

command. The command below will be helpful

If there is GNU compiler on the system. Then you will receive a positive reply. Because you can see a 

message on the screen. In case, your system does not have GCC. Then do not worry.

Steps to install GCC on Windows

 MinGW from official homepage. To go there click on http://www.mingw.org/

However, you must remember to install the latest version of MinGW installation program only. Most 

importantly, you must install file with following name only. The name is MinGW-<version>.exe.

After this you should add bin subdirectory of MinGW installation. You have to add this to PATH 

environment variable. This way specifying tools on command line will be easy. As you will refer them

 by simple names only. Once installation of program is over. You can run G++, GCC, ranlib, dlltool, ar.

 Even running other GNU tools from Windows command line is easy.

How to install GNU on Mac OS

Installing GNU on Mac OS is very easy. All you must do is go to Apple official website. After that you

 can follow the instructions. Moreover, if you use Mac OS X then you must go
