Memory Leak: Bit-Wise and Member-wise Copy in C++

Earlier versions of C++ (prior to release 1.2) implemented assignment between objects through bit-wise copy of the source to the destination. Consider the following example that illustrates a bit-wise copy.

xxxxxxxxxx

class MyString {    

  public:  

     MyString(int n)  { size = n; rep = new char[size]; } 

     ~MyString()      { delete [] rep; } 

     int length() const      { return size; } 

 private: 

    char* rep;     

    int size; 

  }; /* MyString */

The main program has two objects of class MyString.
