u were to put this class into a library and nce its intuitive. Now suppose yo existence so could take advantage of it. But someone then says to you, "The so that use function so that users that I meant to overload the unary as a The class is fine, except uence of letters in the string and returnis that it reverses the sequence of letters in the str s case t shouldI would be new instance o for the user to derive a new class from the string class and add the reated the capabilities of the original class will still be there, plus the added capabi features, the new class really is a kind of String class. class, all of of more String class with Write a class called ReverseString that is publicly derived from the st class, with the following member functions: a default constructor function a copy constructor function a constructor function that takes a const char as its one argument an overloaded assignment operator . an overloaded unary operator-() function that reverses the letters of the string itself, and returns a new Reversestring instance by value (note that the actual contents of the string literal pointed to by buf are never modified) Write a class called Casestring, that is publicly derived from the String class, with the following data members: a pointer, upper, of type char*, which holds the contents of the string literal in upper case a pointer, lower, of type char, which holds the contents of the string literal in lower case Focus on Object-Oriented Programming with C++ Page 454

Explanation / Answer

#include <iostream>
using namespace std;

class CaseString {
private:
string str;
  
public:
// required constructors
CaseString(){
  
}
  
CaseString(const CaseString &obj) {
char* ptr = (char*)obj.str.c_str();
string str1(ptr);
str = str1;
}
  
CaseString(const char* ch ){
string str1(ch);
str = str1;
cout << "str " << str << endl;
}
void operator = (const CaseString &D ) {
str = D.str;
}
// method to display distance
void print() {
cout << "F: " << str << endl;
}
  
};
int main() {
  
string inputStr ;
cin >> inputStr ;
  
cout << inputStr;
CaseString cstr1((char*)inputStr.c_str());
  
CaseString cstr2;
  
cstr2 = cstr1;
  
// cstr2.print() ;
  
CaseString c1(cstr2);
  
c1.print();
return 0;
}
