Struct

• Array


  A collection of elements of the same data type
• Structure


  • A collection of one or more elements grouped under a single name for easy manipulation
  • Can contain elements of different data types
• Struct


  Keyword that identifies the beginning of a structure
• Writing a structure


  1. Struct keyword

  2. Name of the structure

  3. Members of the structure enclosed in braces

  4. Semicolon to end the structure
• Structure instance


  Declaring structure variables after writing the structure definition
• Accessing structure members


  Using the dot operator (.) between the structure variable name and the structure member name
• Copying information between structures


  Possible to copy information between structures of the same type
• Initializing structure members


  Can initialize member elements at declaration
• Complex structures


  • Structures containing other structures as members
  • Structures containing arrays as members
• Accessing members of structures inside structures

  Use dot operator to access nested structure members
• A structure can be considered as a type for a variable (instance of the structure)
• Structure member elements cannot be initialized with values on the definition of the structure
• Structures containing arrays


  • Structure can contain one or more arrays as members
  • Access array elements using structure variable name and dot operator
• Array of structures


  • Can have arrays of structures
  • Access members using structure variable name, dot operator, and array index
• Initializing structure instances


  1. Can initialize simple structures at declaration

  2. Can initialize complex structures at declaration
• Passing structures to functions

  Can pass structures by value or by reference
• Passing arrays of structures to functions is similar to passing ordinary arrays
