Hey guys I have a kind of perplexing situation that is probably simple, but I can't seem to understand something. I have this code here that is basically a program that solves all 92 eight queens solutions, but prints it out in a 1D array of 8 numbers like an odometer. Each number tells you how many boxes down to go to put a queen inside (You go down the required number of boxes and then put a queen in the next one. EX: 47302516 - you put a queen in boxes 5,8,4,1,3,6,2,7 if you want to think about it from a non-programmer's perspective instead of starting from 0 because of the array going from 0 - 7). Now this program works perfectly fine, but I want to know why I have to declare the "int q[8]; int c;" variables as global for it to work. If I don't, the program just prints out nonsense.
Here is the working program:

Any insight into this would be greatly appreciated for this aspiring C++ programmer :]. I want to know what I would have to change for it to work if the variables weren't global. I know it has to be something with the way I'm passing the variables through the functions, but I'm not sure. Thanks again guys.
