X[j][k][l] What are you trying to do here? X is just a normal Array. And here you use it as a 3 dimensional array?

Edit : in your function, you create int Z[pr][sec][ter]; but then you never use it. You use X which is just a normal array instead of Z.

As i understood, X is a 1D array, but in line 10, you want to get access to X as 3D array!
so, it should be impossible!
its the reason of this error:
In function 'void riga(std::ofstream&, int&, int, int*, int, int, int, int)': 10:13: error: invalid types 'int[int]' for array subscript
