Question

C++

Define a class called Text whose objects store lists of words. The class Text
will be just like the class StringVar except that the class Text will use a dynamic
array with base type StringVar rather than base type char and will
mark the end of the array with a StringVar object consisting of a single
blank, rather than using '\0' as the end marker. Intuitively, an object of
the class Text represents some text consisting of words separated by blanks.
Enforce the restriction that the array elements of type StringVar contain
no blanks (except for the end marker elements of type StringVar).
Your class Text will have member functions corresponding to all the
member functions of StringVar. The constructor with an argument of
type const char a[] will initialize the Text object in the same way as
described below for input_line. If the C-string argument contains the
new-line symbol '\n', that is considered an error and ends the program
with an error message.
The member function input_line will read blank separated strings and
store each string in one element of the dynamic array with base type
StringVar. Multiple blank spaces are treated the same as a single blank
space. When outputting an object of the class Text, insert one blank
between each value of type StringVar. You may either assume that no tab
symbols are used or you can treat the tab symbols the same as a blank; if
this is a class assignment, ask your instructor how you should treat the tab
symbol.
Add the enhancements described in Programming Project 6. The
overloaded version of the extraction operator >> will fill only one element
of the dynamic array.
