Implementing a User-Defined Type Time with a struct

See Figs.1.2-1.3.

• Default: structures passed by value
  • Pass structure by reference; Avoid overhead of copying structure
• C-style structures
  • No interface; If implementation changes, all programs using that struct must change accordingly
  • Cannot print as unit; Must print/format member by member
  • Cannot compare in entirety; Must compare member by member
