Well, int Z[][k] isn’t valid syntax in C. Not as a declaration and not as a parameter. And it certainly isn’t C#.

Furthermore, int A(int [ ][k], int, int); is a forward declaration for a function. It is not a match for the 1st parameter of input_values.

I’m guessing you ended up with this notation for A because it gives no syntax errors. That is because the C compiler just ignores the invalid k in there.
