8. Implement the Dots class shown below that represents a string of zero or more dots (i.e. periods). For example Dots d(4) would represent a string with four dots: ".... Recall, we can add a character to the end of string s using the + or += operator. For examples += '.' adds a period to the end of s. #include #include using namespace std; class Dots { friend ostream& operator=0. Dots operator* (int k) const; // like *=, but don't modify *this. void print (ostream & out, bool endline = false) const; // output s and possibly an endl. private: string s; }; Dots::Dots (int n) string Dots::get() const void Dots::set(int n) Dots Dots:: operator++ (int dummy) Dots & Dots::operator++ ( ) Dots & Dots:: operator*=(int k) Dots Dots :: operator* (int k) const void Dots: :print (ostream & out, bool endline) const
