WebC++ Structures. Structures (also called structs) are a way to group several related variables into one place. Each variable in the structure is known as a member of the structure. Unlike an array, a structure can contain many different data types (int, string, bool, etc.). WebDec 2, 2016 · 1. If the structures are mutually recursive, then put a forward declaration for both, as: struct Building; struct Room;. Subsequently you can declare pointers to either struct as needed. Typedefs will neither help nor hurt; it's the forward declarations that will help. – Erik Eidt.
