I have an int array myArray[x][y] and I wish to pass this to a function by reference, but it seems like it either needs constant bounds or some odd pointer workaround? How do I do this properly?

An array with automatic storage duration always requires compile-time constant bounds. The fact that you can do
int array[x];wherexis not a compile-time constant in GCC is merely a non-portable extension. Indeed, you cannot pass such a non-standard array by reference to a function.You could just pass the bounds along with the array, but you’re much better off using a standard container such as
std::vector.
