NettetAs I see it int *x [n] [m] declares x to be a 2-d array of pointers to integers, so allocating memory should be as easy as x [i] [j] = new int and as expected it works fine. Now if I change the declaration to: int (*x) [n] [m] x [i] [j] = new int no longer works and results in a compilation error.
