Create a class called Line with the followings:
1. Private members: p1 and p2 as pointer to Point objects (code provided below), slope and length as double variables
2. Define setter and getter functions.
3. Define a default constructor that allocate dynamic memory for points and
set everything to 0.
4. Overload a constructor that allocates memory for points, initilize them
with given arguments, and calculate the slope and length.
5. Overload a destructor, a copy constructor and a copy assignment operator.
6. Create a function called ”parallel” that return true when given lines are
parallel and returns false otherwise
7. Overload the less than (<) and="" greater="" than="" (="">) and equality (==) oper-
ators (compare the length)
8. Write a functions that reads lines in the format provided in the lines.txt
from the file and stores them in a vector named Lines.
9. Sort the objects of Lines vector in descending order.
10. Extend the functionality of cin and cout for this class
11. Write a separate file to extensively test your code as you learned in unit
testing lessens.
