Hello,

My first question is one which is halting me and has already been posted about a few times (here and here) but is still yet to be answered. This is regarding the evaluation of non-returning functions. Can these be assumed to be equivalent to 0, or should assigning them cause an error?

The second is in the inconsistencies between how functions are called between examples. In Sample 6 we see the following:

print multiply(12, 6)

with no space between the function call and the brackets with parameters. However in Sample 5 there's this:

printsum (12, 6)

Where there is clearly a space between the two. Which is the right option?

Finally I have two questions about error handling given that there has been no error handling taught thus far within the unit. First- is a standard error message using perror with an undefined error 0 adequate? Such as:

[Custom error message]: Undefined error: 0

Lastly, does every error have to be handled by runml? Are there some errors that are able to be picked up within compilation of the C file, or does every error have to be dealt with specifically by the compiler we've written?

Thanks.
