This prints a 3D array of integers, I need to write a function called tick that returns the element of user specified coordinates i j k. That part of the code is this

when I have this in my code, it doesnt print out the 3D array and I get a segmentation fault when it's supposed to print the element. Any Ideas? Thanks in advance
