:   I apologize--I'm a little new to C. Can anyone tell me why this
:segment of code produces an output of 900 when it is suppose to be 5?
===========
int attributes[1,1,1] uses a comma operator. This is not the way to do
multiple dimensions in C ( comma operators, where legal, represent
an ordered set of evaluations and the value of 1,1,1 is just the result of
the last evaluation: 1).  If you mean a 1x1x1 object it is declared
    int attributes[1][1][1];
Notice that there is exactly 1 element in a 1x1x1 object, namely
    attributes[0][0][0].
