how to compile a c program in Linux

Hi guys,

I'm a C newbie. I'm learning C programming under Linux environment. I'd like to know how to compile and run a program programA.c, which #include "programB.h". I've programA.c, programB.h and programB.c all in one directory.

Do I have to compile programB.c first?

I try this command "cc -o programA programA.c" but it didn't work?

Can anyone help, please. Thanks

Code:

---

gcc -o program program.c

---

i dont really know the difference between those two.
some time ago i was used to cc. now i got used to gcc.
my two cents. ;)

here is a page at my school that can explain how it dependencies work and how to create a make file better thatn I can.....

But still a common question (but it never annoyed me) :D
My main.c includes stdio.h, in which function prototype e.g. printf() is declared. But I don't have source code for printf's body.
How does `$ cc main.c' works without compiling body?

If I have several headers.h and several bodies.c, how do I compile like above i.e. `$ cc main.c' only without compiling bodies?
