Lecture 12.2: The mechanics of function calls (part 2) - Richard Buckland UNSW

How C function calls are implemented - at the machine code level. The role of the callee. Frames. Saving registers, local variables. one way of returning a value.

Also: following safe conventions even when we don't have to do so. The danger of having to think. The lunch box scope example completed. Can you ever have too many comments? The address of operator &.

This is the second part of Lecture 12.

We finish early which leaves us time to chat about another key person in the development of the science of computing - Alan Turing (see Lecture 12.3 which follows)

Did you ever come back to the Halting problem? I haven't been able to make heads or tails of the wikipedia article, but I'm very interested.
