There are 5 fundamental data types :

Integer 
  int  

Character 
char 

Floating Point 
float 

Double precision floating point
double 

Void

IN Window Size of pointers int 4 void 4 float 4 double 4 char 4

In Linix Size of pointers int 4 void 4 float 4 double 4 char 4

There are no difference bewteen the size of pointers of the data types. And the size of pointers are same in Win & Linix

int x;
int y;
printf("pointer_x = %p,pointer_y = %p,(long)(&x-&y)=%ld\n",&x,&y,(long)(&x-&y));
printf("(long)&x-(long)&y=%ld\n",(long)&x-(long)&y);

In linix

pointer_x = 0x22ccb0,pointer_y = 0x22ccac,(long)(&x-&y)=1
(long)&x-(long)&y=4

In window

pointer_x = 0xfff1a9d8,pointer_y = 0xfff1a9d4,(long)(&x-&y)=1
(long)&x-(long)&y=4
