How to Run C Program in Linux Environment

Note : This tutorial is for those who used to write programs in Windows Environment and want to write programs in Linux Environment.

Steps :

1.Write Program

• You can type C program using any of the editors that are available under Linux.
• VI and EMACS are two famous editors in Linux.
• I have Written Sample Code in Fedora 7. [Application -> Accessories -> Editor]

2. Save Program

• Save your C program with .C Extension .
• Open Prompt or Terminal .
• An ls command will display your C program.
• Now at the prompt type the following
  

$ gcc -o mypgm mypgm.c

• Suppose your file is named mypgm.c then type ‘-o mypgm ‘ as the parameter to gcc.
• Mypgm is name for the executable file that gcc would create.

This Process can be Split into Two Processes -

Step 2.1 :

$ gcc mypgm.c

• You would be having a a.out in the same directory as the source C file.
• This is the default name of the executable that gcc creates. [ This would create problems when you compile many programs in one directory. So you override this with the -o option followed by the name of the executable ]

Running the executable that you created is as simple as typing the following at the prompt.

$ ./mypgm
