A struct in the C programming language (and many derivatives) is a composite data type (or record) declaration that defines a physically grouped list of variables under one name in a block of memory, allowing the different variables to be accessed via a single pointer or by the struct declared name which returns the same address. The struct data type can contain other data types so is used for mixed-data-type records such as a hard-drive directory entry (file length, name, e… 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.
