storage class is an
attribute that changes
the behaviour of a
variable

There r 4types of
storage classes.They
are
auto
static
extern
register

auto- auto is the
default var type.
ex int x=1 and auto
int x=1 both r same

static- static
variable is a
variable,with in the
scope when it reaches
the initialization it
blindly igores and
hold the updated value

register-reg var tells
the compiler that the
variable will be
heavily used.It is
stored in cpu register

extern- extern var
tells that they have
allocated space in
some other program.
But just using here.
We cant initialize
using extern
