how to combine more than two programs....

[cworld]

i have written a program in C for RPN calculator. In this i have made four function and a main ( ) and stored in same file. But now i have stored each function in a different C file and one header file and want to run it.
So i am getting some errors. My doubt is that whether i have to run each file before i run Main file OR whether i should make headre file more than one.
I have stored all file in the same folder. Help me !! or suggest me some reference!!!
Thankyou

Create a project and add all source files and header files..... and run the project

the simplest way is to put function prototypes for all the functions in your C files in the header and include the header in all the C files. Do you have global variables which are used by functions in different files, if so you declare them extern in the header. have a look at

which compiler are you using?

Thankyou sir,
I am using VC++.I will declare the variable in header file as extern variable. It means i need one header file in which i can declare variables then include the header file in each file. So then do i need to compile each program separately other than main file.
thankyou in advance to clear my doubt once again.

I don't use VC but I assume you have to create a project which contains the C and C++ source file. When you tell the compiler to build the project it should compile all files that are not up to date and link them. Perhaps a VC expert can advidse here?
