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.
