But if you then use that pointer to point to a non-const you will probably get the error (or its converse) there instead! I don't know if it would generate an error if you pointed it to a non-const, but as soon as you tried to change the value it pointed to you would get an error. Andy Neil said:
That's the basic flaw: Stefan is trying to use a single pointer to point to both const and non-const objects... If he wants one pointer to do both (point to a constant and non-consant), then he has a problem. The reason I posted the explanation was because I wasn't sure if he knew there was a way to declare a pointer to a const. |
