Thinking in C++

Pointers can be made const. The compiler will still endeavor to prevent storage allocation and do constant folding when dealing with const pointers, but these features seem less useful in this case. More importantly, the compiler will tell you if you attempt to change a const pointer, which adds a great deal of safety.

When using const with pointers, you have two options: const can be applied to what the pointer is pointing to, or the const can be applied to the address stored in the pointer itself. The syntax for these is a little confusing at first but becomes comfortable with practice.
