Create 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 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 functions that reads lines in the format provided in the lines.txt(provided below)

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 separate file to extensively test your code as you learned in unit

testing lessens.
