Size of pointer

Question

I have following code
int *p,a;
a=10;
p=&a;
printf ("size of p %d\n",sizeof (p));
printf ("size of p %d\n",sizeof (*p));
output:
8
4
so what size of pointer p should I consider 8 or 4
and also please answer why ?

Answer 1

Int is treated as 64 bit number, so 8 bytes. Pointer to int is 4 bytes.

Answer 2

But if p is treated as int then why it's size is not 8 byte

Answer 3

and what size should I consider when someone is referring to address of pointer

Answer 4

p is a pointer to an int, not an int. Think of it this way: you need less space to store an url than the content of the page. But some machines will have 64 bit pointers

Answer 5

I got it
as I'm compiling on 64 bit machine
address is going to b 64 bit so sizeof (p)
is address where as sizeof (*p) is size of intiger a

Answer 6

But I think sololearn uses a 64 bit compiler, so i think the pointer should also be 64 bits, but thats not the case.

Answer 7

If its 64 bit then memory addresses associated with variables will also be 64 bit then 8 output is correct
and pointers always have size equal to intiger type anyhow.

Answer 8

then your question is not answered.
