Design and code a class named Paragraph that holds information about a paragraph.  Upon instantiation, a Paragraph object may receive a null-terminated C-style string.  If the object receives such a string, the object accepts the string without modification as a paragraph.  If the object does not receive a string, the object stores a safe empty state.  The object adopts a default output width of ten (10) characters.  Your class does not impose any limitation on the number of characters in a Paragraph object.  Your design includes all of the member functions needed to accomodate this feature under a variety of applications, including the one below.

Your class also includes the following functions:

• clean() - a query that returns the address of the first non-whitepsace character in the Paragraph object;
• clean(int i) - a query that returns the address of the first character of the i-th word in the Paragraph object, where a word is a contiguous set of non-whitespace characters; and
• width(int) - a modifier that receives an integer holding the number of characters to be displayed on a single line of output; if the integer is invalid for any reason, your object adopts the default number of characters;
• an insertion operator that inserts the entire paragraph (with leading spaces, if any, included) into an output stream.

 #include <iostream>
 using namespace std;
 #include "Paragraph.h"
 int main ( ) {
     Paragraph a, b("   This is OOP244.  Next is BTP300.");
     b.width(20);
     cout << b << endl;
     a = b;
     cout << a.clean() << endl;
     cout << a.clean(2) << endl;
     cout << a.clean(4) << endl;
     return 0;
 }

    This is OOP244.
 Next is BTP300.
 This is OOP244.  Next is BTP300.
