3. Kinds of coupling

• Encapsulation

  
      class Employee {
          std::string m_name;
      };//class Employee
  
  

• Inheritance

  
      class Manager : public Employee
  
  

• Simple use (as client)

  
      Account acct1;
      acct1.deposit( 1000000 );
  
  

• Template instantiation:

  
      std::map< std::string, int > phone_directory;
