Review Questions

1:	Consider the following class declaration: class RQ1 { private: char * st; // points to C-style string public: RQ1() { st = new char [1]; strcpy(st,""); } RQ1(const char * s) {st = new char [strlen(s) + 1]; strcpy(st, s); } RQ1(const RQ1 & rq) {st = new char [strlen(rq.st) + 1]; strcpy(st, rq.st); } ~RQ1() {delete [] st}; RQ & operator=(const RQ & rq); // more stuff }; Convert this to a declaration using a string object instead. What methods no longer need an explicit definition?
2:	Name at least two advantages string objects have over C-style strings in terms of ease-of-use.
3:	Write a function that takes a reference to a string as an argument and which converts the string to all uppercase.
4:	Which of the following are not examples ...
