Answer / kishor narayan
Volatile qualifier indicates to the compiler that the
variable can be modified at any stage of the program
execution. This can happen even if the region of code being
executed might not have any access to the variable in
question. In that sense, Volatile qualifier does the
opposite of the Const qualifier.
@Vignesh1988i -> Volatile qualifier does not assign any
garbage value to the variable.

it is the variable which can be modified outside of the
program. i.e hardwares can modify this variable. To avoid
compiler optimization we can use volatile.
this is used for memory mapped hardware and shared memory
usuage.
