(P876 from textbook C++ How To Program:)The volatile type qualifier is applied to a definition of a variable that may be altered from outside the program (i.e., the variable is not completely under the control of the program). Thus, the compiler cannot perform optimizations (such as speeding program execution or reducing memory consumption, for example) that depend on "knowing a variable's behavior is influenced only by program activities the compiler can observe."(notes:)1) volatile indicate the object is modified by something not directly under the compiler's control (i.e., the hardware itself)2) one use of volatile qualifier is to provide access to memory locations used by asynchronous processes such as interrupt handlers.3) Another example might be the global variables that keeps track of the total number of timer interrrupts.
