Write a program in C++ object oriented programming Create a class Class1 with a string data member ‘paragraph’. Provide a constructor and getParagraph() method in the class. The constructor just assigns NULL to the data member. getParagraph() method must read a paragraph from user. The paragraph should contain at least 30 words. If there are less than 20 words, the program must ask user to enter paragraph again. Create another class Class2, and make it a friend of the class Class1. Provide a function getSubString(Class1 &obj1, int startIndex, int lastIndex) with return type string in the class Class2 which accepts an object of class Class1 (by reference) and two integers. The getSubString() function should return the substring starting from location startIndex and ending at location lastIndex. Class2 must also contain a store() function that stores the substring in a file. Print screenshot of substring stored in file as well. (Topics covered: File Handling, Friend Classes.
