C Strings in C++ and Deep Copies

I was told on Stack Overflow:

“A pointer is just a pointer.”

And that is true of course. To go beyond that we have structures and classes which have explicit construction and operators. However, C++ has inherited C strings which are just a pointer to the first char, but they also have a long history where the construction and operations are well known. So, when a C String is given to a map or vector, it may be thought that it could be doing a deep copy. After all, it is known (by implicit rules) how this could be completed. The size is defined. It is just not stored. Also, the storage is clear – just not managed.
