Answer / test
Voliatile means value can be changed at any point .when we
say cont volatile it says value cant be changed by the
programer but can be changed by the hardware ..
for example status register of any hardware ..
its volatile since value of this register can changed at any
time and its const too since its not changed by the programmer.

Answer / n
read-only data which should not be optimized by compiler
because it might be modified by some ways unknown by
compiler.(ex: HW, or even by other thread if we have const
volatile int *p for example, where p is the address of some
variable which is not const).
