Question
Is any difference there b/w global and extern variable, if it there can u explain?
First of all there is no keyword called "global".
extern keyword will tell the compiler that the definition of this variable is made somewhere else and you can use this declaration for your information.
And this variable has to be global (means declared outside main function). Otherwise, extern will be of no use.
So, global and extern are not same.
