I am trying organize my code and make it more readable and eazy to debug.
I have my constants in a header file and I need to use this in 2 .c files. Now I am getting the "Multiple public definitions" error.

How do I deal with this.

If the variables and functions are declared in header file then use extern specifier in .c files.

I have defined my constant char array in a header file.
These are used in 2 source files.
Now I have to declare them as extern const char in the second source file or should I declare as extern in all the source files which use them?

Let me try to understand this -
When I declare the const char array in a header file, this is both declaration and definition(memory is allocated).
In the source files when I use extern...., this is only declaration. Correct?
