Literals

A literal in computer science is used to express a fixed value in source code. They cannot be modified. Almost all programs have these fixed values or literals.

Textbook Question

Chapter 9, Problem 9.12PE

(Geometry: intersecting point) Suppose two line segments intersect. The two endpoints for the first line segment are (x1 , y1) and (x2, y2) and for the second line segment are (x3, y3) and (x4, y4). Write a program that prompts the user to enter these four endpoints and displays the intersecting point. As discussed in Programming Exercise 3.25, the intersecting point can be found by solving a linear equation. Use the LinearEquation class in Programming Exercise 9.11 to solve this equation. See Programming Exercise 3.25 for sample runs.
