A pointer to a const object, on the other hand, can be reassigned to point to another memory location (which should be an object of the same type or of a convertible type), but it cannot be used to modify the memory that it is pointing to. A const pointer to a const object can also be declared and can neither be used to modify the apointee nor ...
Memory protection can be applied to this area to prevent overwriting of such constants by errant pointers. These constants differ from literals in a number of ways. Compilers generally place a constant in a single memory location identified by symbol, rather than spread throughout the executable as with a macro.
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.

"It served two functions: as a way of defining a symbolic constant that obeys scope and type rules (that is, without using a macro) and as a way of deeming an object in memory immutable." const was then adopted in C as part of standardization, and appears in C89 (and subsequent versions) along with another type qualifier, volatile, which was ...
