MULTIPLE PUBLIC DEFINITIONS

Affan Rauf

I define a variable 

unsigned char c
 in a file A.h and include it in A.c and another file B.c in which the variable is being used.

Then I face a linker error of multiple public definitions.

PS: The variable is declared once for sure.
    The usual way of making header files is used. 
#ifndef
 etc.

Can anyone help me remove this error? I'll be very grateful.
