  automatics?         


Author: kevincw01

My professor mentioned using automatics in a C program and I've never
heard of them. Searching google came up with nothing (besides
automatic cars). What are they?

Thanks, -Kevin

No. But if you are looking for other front ends, you might consider

  C parser wanted         


Author: David Given
Date: Feb 25, 2007 01:14

I'm trying to write a C source transformer, that will read in ANSI C source
code, mutate it in various bizarre ways, and then write it out again.

Unfortunately, C is notoriously hard to parse due to context-sensitive tokens.
Does anyone know where I can find a simple-as-possible toolkit that will
construct a parse tree and emit it again? Ideally I need something actually
*in* C, which lets out cil and the antlr-based grammar. I have found ctree,
but it's not really open source and it's a bit cryptic.

Does anyone know of anything else I should look at?

"Old" as in "of legal drinking age by now" (in quite a lot of
countries), that is.

see whenever you are reading a string the name of the string itself
gives the address of the string variable and is the reason for not
using "ampersand" before string

  i cannot do the code for this program...         


Author: newbiejake
Date: Feb 21, 2007 23:50

I need a code that at first how many courses did one take. then if you
answered for example "5" it will ask you 5 times of the course name,
the number of units, and the final grade for that unit. then after
that the output will show a table-like output which shows everything
you entered and then the Average is also included. but the average
depends on the number of units of that course. some are 3 units and
some are 5 units... i'm not sure if im missing something but any kind
of help will do...

You can try LLVM - http://llvm.org/

Good luck!

Struct assignment and auto aggregate initialization were not supported
in many old C compilers.
