Pointer to a Constant vs. Constant Pointer

Pointer to a Constant vs. Constant Pointer

The const keyword in C++ provides a type-safe way to replace some of those #define preprocessor statements that you’re used to writing from C.Whenever you have a value that you do not wish to have changed, you should declare it as const. For example:

 const int i = 12; // any further attempt to alter i will cause an error.

However, when pointers are involved, what is actually constant depends on where you place the const keyword. Also, the syntax can be slightly confusing.
