Make a file called abc.h





Put your function in it.





Include abc.h into your source file using the preprocessor directive:- #include "abc.h"





If abc.h is in the same directory as C/C++ source file no need to give path else give path.
Reply:Create a file filename.c that includes your own functions, but without a main() function being defined.


Compile it. An error appears saying "main moudule


missing."


This indicates that .obj file of your C program is created.


Now you can use #include "filename.c" as a header.


See to that your filename.c file is placed in the current directory.


Thank you.
