Summary

1And 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)

4.1Conceptual Review¶

1. True/False: In compiled languages, the compile time is generally pretty fast, however the run-time is significantly slower than interpreted languages.
