Make the code compatible with c++ compiler

if we write "int i;" in header file, c compiler treats
as a tentative definition while c++ compiler
treats as a definition.
so when two cpp file includes the same header file
then during linking time compiler says that there are
multiple definitions.

so to overcome this problem we are declaring it as extern
and defining it in the corresponding c file.
