As told in many replies, volatile specifies that the 
variable's contents can change between its use in the program. 
However, volatile allows you to add another level of checking, 
too. For instance, if you know that your program should never 
change the variable's contents (eg. a memory location for a 
real-time clock value), you can use const volatile. Thus, the 
compiler will check at compile time that your program will not 
modify itself the value, but will prevent optimization of 
using the value once read.
