Write a string class. To avoid conflicts with other similarly named classes, we will call our version MyString. This object is designed to make working with sequences of characters a little more convenient and less error-prone than handling raw c-strings, (although it will be implemented as a c-string behind the scenes). The MyString class will handle constructing strings, reading/printing, and accessing characters. In addition, the MyString object will have the ability to make a full deep-copy of itself when copied.

#include <iostream>

using namespace std;

#ifndef _MYSTRING_H_

  int length();

  friend ostream &operator <<(ostream &out, myString &s);

  friend istream &operator >>(istream &out, myString &s);

  bool operator <(myString &s);

  bool operator <=(myString &s);

  bool operator >(myString &s);

  bool operator >=(myString &s);

  bool operator ==(myString &s);

  bool operator !=(myString &s);

main. cpp:

#include "myString.h"

#include <iostream>

using namespace std;

  myString s1, s2;

  cout << "Enter first string: ";

  if(s1 < s2){

      cout << s1 << " < " << s2 << endl;

  }

  if(s1 <= s2){

      cout << s1 << " <= " << s2 << endl;

  }
