C Programming–In Linux (Step By Step)

If you are new to linux and want to right your C programs in this platform, then this post will help you out.You don’t have to know linux in order to write your C programs on this platform.Just follow these steps:
Before getting into the steps let me remind you I am using “Fedora 15”.A newer version of Fedora is available “Fedora 16” you can try it too.So now we are ready to rock and roll.
Step 1
Go to Application -> System Tools –> Terminal and then click on “ Terminal

Step 2
A terminal window will pop up.
Now we need an editor like “Notepad” in Windows to write our codes.So, to do that we will use the vi editor,a built in text-editor in Linux.
Just type vi followed by name of your C program and hit enter.
For example
vi  SimpleProgram.c
Screenshot-18
A vi editor screen will appear.

Step 3
Then just press “ i ” on your keyboard to get into the “ insert mode.Now we are ready to start coding.

Step 4
Now let us write a simple program

Step 5
When you are done with your C coding and want to exit from the vi editor screen just press
Esc” key and then type “ :wq “ and hit “Enter”.

Step 5
Now we will again return to terminal screen

Step 6
Now we will compile and run our “SimpleProgram.c”.To compile just type
gcc  –o Object_Name  C_Program_Name
For example
gcc  –o Simple_obj  SimpleProgram.c
Screenshot-19
After successful compilation a Object file will be created based on your Object Name.In this case
Simple_obj

To run your c program just type
./Object_Name “ and hit “Enter
For example
./Simple_obj
Screenshot-21
The Output will be printed on the Screen.
This is what to need to do in order to write and run your C program in Linux.
