I think it's generally a good idea to avoid declaring multiple variables in the same line (unless you have a very good reason). The space you "save" isn't worth the maintainability penalty. This is a habit I have from C where int* a, b declares "a" as ( int* ) and b as ( int ). Instead, I just write int *a; int *b;
