But in the example I gave, the memory *is* written to later.
A const * pointer lets a C program have a read-only window into memory
that other parts of the program can write to, which can be a useful
thing to have. In C and C++, "const *" doesn't mean a pointer to storage
that does not change; it merely means a pointer that can't be used to
write the referenced storage.
