The different storage types in C++ are
Auto: all the variables declared in C++ are of the type
auto by default
The scope is limited to the loop

int temp; //is by default of type auto

Register: tels the C++ compiler to allocate some storage in
the registers.They are supposed to be faster then other
storage types.

register int var;

Only nonstatic， local variables may reside in registers，
and C++ uses the same rules for register variable scope and
initialization as it does with automatic variables

Mutable:const memebre functions or data types can be
modified using mutable keyword.

mutable int i;

static:static variable is declared as a member of a class,
then it will preserve the value for all the objects of the
class.i.e, one copy of this data variable will be shared by
all objects of the class.

static int temp;

extern : extern keyword is used to specify that the
variable is declared in a different file.Used mostly to
declare global scope

extern int num;
