Assignment #2

INSTRUCTOR: Pawan J. Lingras

• Create a class called user_type with three data members of the type string called:
  
  username, first_name, last_name.
  A constructor that accepts first_name and last_name as parameters. The username is created by taking the first two characters of first_name followed by first six characters of last_name. If last_name is shorter than six characters, entire last_name is used.
  
  Provide three additional functions to return the three data members called:
  get_username(), get_first_name(), get_last_name().
  
  Test your user_type using a small driver program.
  
• Overload input and output operators for the user_type. Test the operators by modifying the driver program.
  
• Create a type called database which contains the following data members:
  
  an array of user_type,
  number of records in the database.
  
  The access function members include:
  
  database();
  int size();
  void append(user_type u);
  user_type operator[](int i);
  
  Constructor initializes the number of records to zero.
  size() returns the number of records.
  append() appends u at the end of the database.
  The index operator returns i-th record.
  
  Write a small driver program to test all the member functions.
