Write a program that finds the point of intersection and the angle between two lines in 3D as follows: 1. Greet the user and ask her/his name. Store the name in a variable. 2. Ask and store parameters a1, b1, c1 of the first line. 3. Ask and store parameters a2, b2, c2 of the second line. 4. Show the equations of both lines by replacing the values a, b, c with the parameter values entered above. The equation of the line in 3D has the form: ax by c
