converting a pointer to a non pointer type

Question

What exactly happens when you convert a pointer to a non-pointer type?
For example:

int i = 7;
int *y = &i;

printf("%x %d %x", y, (int)y,7);

The result when compiled and run is:

29ff00 2752256 7

But what actually resulted - where did the number come from? Is it a random number or something related to what the pointer held?

Does it have a mathematical value such as the address or is the value of the pointer converted by some standard?

Answer 1

2752256 is the decimal value of the memory address 29ff00. You'd get a similar result with

printf("%x %d", y, y);
