Compiling C codes in Ubuntu

Question

I'm a rookie programmer and trying to compile a C code in Ubuntu. I already installed GCC. How do I proceed from here?

Answer 1

You can compile from following command :

$ gcc -o object-file C-source-file

Then try to run :

$ ./object-file

For C code you can use cc command too also you can use g++ for C++.

Once your code becomes more complicated and you start using more and more files, the above will become cumbersome and you'll want to look into "makefiles". They work for small projects too, so the sooner you become familiar with them, the better. If you later code in C++, you will also likely use these.

Answer 2

In a terminal (press Ctrl+Alt+T to open one):

1. Change the directory to where you have saved the .c file using

   cd path
   

   command

2. Type the following command and change the fileName with yours

   gcc -o c-fileName fileName.c
   

   You can write any name instead of c-fileName.

3. Then to run your file type

   ./c-fileName
   

   in terminal.

Answer 3

or you can compile your f.c file from console:

gcc f.c -Wall

then run :

./a.out
