Levels of Pointer

Let's say a variable 'a' is level 0. Then *a may be called of level 1 and **a level 2, etc. &a may be called of level -1 and &&a level -2 following the similar trend.

Representation of instantiated variables as a number

Let's say we have two blocks of code represented by two rectangles below:

And if they contain variables of differing levels of pointer like:

BLOCK 1:
char *d;
char **e;
char f;

BLOCK 2:
int **a;
int *b;
int c;

Then they may be represented by two numbers, one for each block of code:

120 210.
