So let's write it! private static System.Array ToSystemMatrix<T>(ILInArray<T> A) { using (ILScope.Enter(A)) { // some error checking (to be improved...) if (object.Equals(A, null)) throw new ArgumentException("A may not be null"); if (!A

Why does - void display(int p[][SIZE]) // allowed and void display(int p[][]) // not allowed ? 回答1: Because arrays decay to pointers when passed to a function. If you do not provide the cardinality of the second dimension of the array, the compiler would not know how to dereference this pointer. Here is a longer explanation: when you write this p[index] the compiler performs some pointer arithmetic to find the address of the element that it needs to reference: it multiplies index by the size of p 's element, and
