Q about C pointers on pointers.

An awesome example from the challenge. What is the type of p5 pointer and how long does it continue? https://code.sololearn.com/c8rRs6E4BECQ/?ref=app

5x pointer of pointer of int. You can do this as many times as you want. But that is useless, although possible.

This all works good. printf("%d\n",*****p5); printf("%d\n",*(****p5)); printf("%d\n",****(*p5)); What's this?

More over, this also works good. int* q1 = &a; int* q2 = &q1; int* q3 = &q2; int* q4 = &q3; int* q5 = &q4; printf("%d",*****((int*****)q5));

~ swim ~ This approves duck test lol. Think its just pointers. The magic lies in the order of referencing and dereferencing operations.
