A Easy Question From a Beginer

This is my first time in CGI, i need to develop a app that stores the fields of a form in a file in the server

I'm thinking in using C/C++, i've been told that CGI is about parsing the parameter passed to the application!

If this is true, i can build a dos based C/C++ app that will parse the argv parameter and write the values to a file, is that rith??

If that's ok, i need to know how are the values of the form fields passed to the app, and how can i give the user a response??

please if you can do provied me with c/c++ examples!

First Question is what kind of server you're running on.  But, regardless of that you can find a good generic C library for handling all the parsing / decoding at .  After you've read the form input, saved  it or whatever you simply return a stock webpage to the user by using the Location HTTP header or using a

perl is so easy for parsing text. I'd say it is the only way to go.
or you can use perl in your c code.

PERL is nice, but a compiled C script is at least twice as fast and your source code is protected.

as far as speed goes, you only get the hit for compilation after that it is on par with c, and with isapi and such your perl code only compiles once then runs in memory on any other calls to your code, your perl code is also protected, remember it gets executed not sent to the browser.

typicaly the form info is so small it is like using a hammer to kill a fly if you write such a think in c, anyway c is way too clumsy when it comes to text.

Average Run Time for a comparable compiled CGI will always we faster than an interpreted script. No arguements allowed.  As far as protection goes, I'm refering to protecting your code from theft / alteration by others --- either client , host or what have you.  But Yes --- if all you need is a basic form response then perl is much easier.  But if you are even a descent C programmer, you can do just about anything you want with CGI's in C/C++.

not saying you couldnt, just that...

1) easier (typically one paragraph, c 3pg)
2) compiled (speed)
3) not clumsy (text)

nothing is 100% safe from theft on computers. and have you heard of decompilers.

You know c is great for large scale apps but ypically when working with forms or internet apps it is really over kill.  We arent building some realtime 3d graphics engine, thats when c shines.  However you could allways beat it with assembly. <gr>

BTW. you can embed perl in c.
best of both worlds.
