What is the benefit of using const for declaring constants?

The benefit of using the const keyword is that the compiler might be able to make optimizations based on
the knowledge that the value of the variable will not change. In addition, the compiler will try to ensure that
the values won't be changed inadvertently.

Of course, the same benefits apply to #defined constants. The reason to use const rather than #define to
define a constant is that a const variable can be of any type (such as a struct, which can't be represented by
a #defined constant). Also, because a const variable is a real variable, it has an address that can be used, if
needed, and it resides in only one place in memory.
