Alength member function that returns the number of characters in the string. use construction of a mystring from a const c-string. you should copy the string data, not just store a pointer to an argument passed to the constructor. constructing a mystring with no arguments creates an empty mystring object (i. e. ""). a mystring object should be implemented efficiently (space-wise) which is to say you should not have a fixed-size buffer of chars, but instead allocate space for chars on an as-needed basis. use printing a mystring to a stream using an overloaded < < (insertion) operator, which should simply print out its characters. use < < . your mystring object should overload the square brackets [ ] operator to allow direct access to the individual characters of the string. this operation should range-check and assert if the index is out of bounds. you will write two versions of the [ ] operator, a const version that allows read access to the chars, and a non-const version that returns the client a reference to the char so they can change the value. all six of the relational operators (< , < =, > , > =, ==, ! =) should be supported. they should be able to compare mystring objects to other mystrings as well as mystrings to c-strings. the ordering will be based on ascii values. you can think of this as essentially alphabetical order; however, be
