1st project Syntax checking (all 4)

7:59pm Mon 26th Aug, ANONYMOUS

Hi, I was wondering if some of the syntax checking can be left for the c compiler to handle. For example, As I understand the requirements, we don't need to check if functions are defined before being called, since the c compiler will check and report the error anyway.

Your understanding is the wrong way around. An ml function *must* be defined before it can be called. The C code generated by your runml program should not have any C syntax errors, so the C compiler should not find or report any errors in the generated C code.

When it means checking the syntax, do we have to check for all cases, eg if we have a comment in the middle of a print call print incre#ment(3) + increment(4) TIA.

No, because we are assuming expressions are valid and don't need to be checked.
