Thread: Class interdependency circle

I've got two classes: matrix, and ffbyte. They both work fine, and ffbyte is loaded as a header in matrix, which is a header in main.

The elements in the matrices are ffbytes. This works fine, except... I want to make a function in ffbyte that has a return type (and uses inside) a matrix. Because ffbyte is declared before matrix, it won't let me do that. And I can't put it the other way round, because the matrix elements must be ffbytes.

Is there any way of resolving this?

Does it have to be a member function? Can it be a plain old function (possibly a friend) that takes a matrix argument (or whatever) and returns a ffbyte?

I actually figured this out just now...

putting

class <classname>;

at the top of the file, works like the prototype functions in the classes. Fixes my interdependency issues.
