Okay, so I don't know much about this and maybe that is why the doubt. I am pretty sure there must be some precaution if some one tries to create (can say a virus) like this :

   /* creat system call. to create files continuously. Not difficult to give different file name each time */

Inode list doesn't get exhausted here right? But what is done to avoid this ? Or does it mean that we cannot create anymore files?

You might be knowing that the system(OS) would not allow you to create those many files.It will flag you a message that says memory is low,delete some data.

It means that someone could mess up with any machine then. i would run my program on someone else's computer and create trouble for him. But this should not happen , right?? Does system take any care for this ?
