Lesson Ideas

[baines]

Some ideas for future lessons:

• Different uses of pointers

  • Returning multiple values from functions
  • Passing arguments by "reference" instead of by value
  • Optional values with null pointers
  • Arrays of multiple dimensions

• Structs & Unions

  • Storing arrays of records
  • Linked lists
  • "inheritance" via unions & struct pointer casting

• State machines

  • Using an enum & switch statement in a loop to parse complex messages

• Advanced Functions

  • va_args
  • Function pointers

• Macros

  • Differences from functions
  • Multiple evaluation caveats
  • Pasting and stringification
  • __VA_ARGS__
  • GCC/Clang extensions? (statement expressions etc)

• C99 specifics

  • VLAs
  • designated initializers
  • compound literals

I will try to get around to doing some of these in the future, but feel free to beat me to it!
If you have other ideas, you can add them here too.
