Re: [Dev-C++] Passing a plane of 3-d array in C

[Per W. <pw...@ia...>]

You can not pass an arbitrary plane of a three-dimensional array.

You can pass a reference to the full array, together with a parameter that
specify if you mean an X plane, an Y plane or an Z plane, and an index
that specifies which plane.

Then the function will itself have to locate the entries in that plane. To
do that, the function must also know the size of your cube in all three
dimensios.

You may have to specify even more parameters if it is important that the
function processes this plane in the correct order, i.e. you may have to
specify u and v vectors, where the u vector may specify that the function
should walk the cube from high z to low z, and the v vector may specify
that the function should walk the cube from low y to high y.
