Describes how to design the class lineType to implement a line. Redo this programming exercise so that the class lineType:

a. Overloads the stream insertion operator, <<, for easy output.

b. Overloads the stream extraction operator, >>, for easy intput. (The line

ax + by = c is input as (a, b, c).)

c. Overloads the assignment operator to copy a line into another line.

d. Overloads the unary operator +, as a member function, so that it returns true if a line is vertical; false otherwise.

e. Overloads the unary operator -, as a member function, so that it returns true if a line is horizontal; false otherwise.

f. Overloads the operator ==, as a member function, so that it returns true if two lines are equal; false otherwise.

g. Overloads the operator ||, as a member function, so that it returns true if two lines are parallel; false otherwise.

h. Overloads the operator &&, as a member function, so that it returns true if two lines are perpendicular; false otherwise. Write a program to test your class.
