Summary

And in Conclusion$\dots$

• C was chosen to exploit underlying features of HW.
  • We will begin discussiong memory management in a lot more detail next time with pointers and arrays.
• C is compiled and linked to make executable.
  • Pro: Speed
  • Con: Slow edit-compile cycle
• C looks mostly like Java, except no object oriented programming
  • Abstract Data Types are defined through structs; more next time
  • bool: 0 and NULL are false. Everything else is true.
  • Use intN_t and uintN_t for portable code!
• Uninitialized variables contain garbage.
  • “Bohrbugs” (repeatable) vs “Heisenbugs” (random)

Conceptual Review

Solution

False. Reasonable compilation time, excellent run-time performance. It optimizes for a given processor type and operating system.
