Structs

Introduction

Structures provide a way to group a set of related variables of diverse types into a single unit of memory. The structure as a whole can be referenced by a single name or pointer; the structure members can be accessed individually too. Structures can be passed to functions and returned from functions. They are defined using the keyword struct.
