Overview

The core of implementing a String class is rewriting constructors and overloading operators.

We need to define:

Original Constructor
Copy Constructor
Move Constructor
Copy Assignment
Move Assignment
Destructor
Indexer
Equal/NotEqual Operator

#ifndef CAMILLE_STRING_H
#define CAMILLE_STRING_H

// using char to store
class String {
  char* str;

public:
  String(const char* s = "");
  String(const String&); // copy constructor
  String& operator=(const String&); // copy assignment
  String(String &&) noexcept ; // move constructor
  String& operator=(String&&) noexcept ; // move assignment
  ~String(); // destructor
  operator const char* ();
  String operator+(const String&);
  String &operator+=(const String&);
  char operator[](int) const;
  char &operator[](int);
  String operator()(int, int);
  bool operator==(const String&);
  bool operator!=(const String&);
};
