   2         Program illustrates stack randomization of operating systems.
   3
   4         Operating systems attempt to prevent security vulnerability by
   5         randomizing the stack location when a program starts.
   6
   7         This helps prevent buffer overflow attacks.
   8
   9         To test and see if this security measure is built into your
  10         system, run this program several times; if the stack address
  11         changes each time, it is likely that this is implemented on
  12         your system.
