Enhance the definition of the class StringVar given in Displays 11.11 and
11.12 by adding all of the following:
■ Member function copy_piece, which returns a specified substring;
member function one_char, which returns a specified single character;
and member function set_char, which changes a specified character.
■ An overloaded version of the == operator (note that only the string values
have to be equal; the values of max_length need not be the same).
■ An overloaded version of + that performs concatenation of strings of
type StringVar.
■ An overloaded version of the extraction operator >> that reads one
word (as opposed to input_line, which reads a whole line). (continued)
If you did the section on overloading the assignment operator, then add it
as well. Also write a suitable test program and thoroughly test your class
definition.
