I don't want my programs to access the file system at all
means no file creation, no deletion not even the a single stream for accessing files.

It seems you are going to prepare FAQS on "How to restrict a program...."

In interpreted language environments, you often have the option to create a "sandbox" interpreter. However, the actual process still has the same permissions and accesses as any other executable process.

For compiled programs like C++, you have to create that sandbox using features of the OS --which, obviously, is entirely platform-dependent.

On windows, you can control group policy permissions and program access rights.

Good luck.

Unique education system! We learnt "how to" and your college asks you to learn "How to prevent".
Pretty advanced! ;)

[gogoc]

no they dont want it
i wan it to do that so that it will become easy and even i can learn some thing

[Ajay Vijay]

But that's not proper way of learning. First learn (if you dont know) how-to do something, then advanced concepts with that, followed by some real world developement.

At codeguru, we offer solutions to some problems (homework assisgments are generally ignored); and not this how NOT to !

Run it on a different machine. Then it'll never be able to touch your filesystem.

Seriously, what possible use would such a restriction be?
