Thanks for the replies.
Nothing is wrong with it, the Prof. wants us to to roll our own, thus
we roll our own :-)
Right. In which case as the others here have said the public interface
should be sufficient. That is to say, you can treat any sort of string
implementation should be treatable as a char array via methods on the
public interface. Take a look at c_str() on std::string for instance
or operator[]. That should give you enough to get going.
The functions he'll doubtlessly need are those concerning
concatenation: + and += (both for string += string and string +=
char).
The prof sounds a bit sadic, however. Writing a correct
conversion (without rounding errors) to and from floating point
is extremely difficult.
