C ENVIRONMENT SETUP

In this article of C ENVIRONMENT SETUP, you gonna learn what you need to write your code and compile that code on Windows, Linux, and Mac Operating System.

In this article of C ENVIRONMENT SETUP, you will learn how to set up environment today as well as how older people used to do the setup for C.

QUICK AND EASY SETUP SETUP 

Similar to any programming, C programming language also needs two things text editor on which you will write your code and compiler to compile that code.

Because without compiling a program, it is just a waste because a computer doesn’t understand the language of human being in which your code your code has been written.

To teach the computer to understand your program, you will need a compiler. A compiler is just a translator which converts human written code that is also called as source code into machine understandable language that is in terms of binary language or numbers.

However, after a successful compilation of source code, you will get an object file with a .obj extension which further gets converted into an executable file. But, after a successful linking to object file by a linker.

Don’t worry you won’t have to do anything. I gonna give you information an awesome platform which lets you do everything without worrying about text editor and compiler.

Installation on Windows

I will be going through code::blocks, however, you can install any IDE like turbo c, clion, visual studio.

Just go on the link below and follow instructions.

code::blocks

Download mingw-setup.exe

NOTE: Download and install compatible software according to OS capacity, for instance, 32 bit or 64 bit.

Installation on UNIX/Linux

I will be going through code:: blocks, however, you can install any IDE like turbo c, clion, visual studio.

Just go on the link below and follow instructions.

code::blocks

NOTE: Download and install compatible software according to OS capacity, for instance, 32 bit or 64 bit as well as keeping care of version of Linux like amd64 or i386 and mainly keep care of flavor of the Linux operating system like Centos, Fedora, distro.

Installation on Mac OS

I will be going through code::blocks, however, you can install any IDE like turbo c, clion, visual studio.

Just go on the link below and follow instructions.

code::blocks

NOTE: Download and install compatible software according to OS capacity.

Older Days People Used To Set Up

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.

The name and version of text editors 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 on Linux or UNIX.

The files you create with your editor are called the source files and they contain the program source codes. The source files for C programs are typically named with the extension “.c“.

Before starting your programming, make sure you have one text editor in place and you have enough experience to write a computer program, save it in a file, compile it and finally execute it.

The C Compiler

The source code written in the source file is the human-readable source for your program. It needs to be “compiled”, into machine language so that your CPU can actually execute the program as per the instructions are given.

The compiler compiles the source codes into final executable programs. The most frequently used and free available compiler is the GNU C/C++ compiler, otherwise, you can have compilers either from HP or Solaris if you have the respective operating systems.

The following section explains how to install GNU C/C++ compiler on various OS. We keep mentioning C/C++ together because GNU GCC compiler works for both C and C++ programming languages.

Installation on Windows

To install GCC on 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 Min-GW, 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.

After 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.

Installation on UNIX/Linux

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 −

$ gcc -v

And If you have GNU compiler installed on your machine, then it should print a message as follows −

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)

What If GCC is not installed, then you will have to install it yourself using the detailed instructions available at https://gcc.gnu.org/install/

This tutorial has been written based on Linux and all the given examples have been compiled on the Cent-OS flavor of the Linux system.

Installation on Mac OS

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. Once you have Xcode setup, you will be able to use GNU compiler for C/C++.

Xcode is currently available at developer.apple.com/technologies/tools/.
