Programming Assignment 1
Due Thursday, Sept. 14
1) Implement and test a Point class. Objects created from this class represent
a point in a two dimension coordinate system or plane. Each point represents
an x and a y coordinate. There are 7 operations that are important for a Point
object. You must be able to create a point from two numbers (floats or integers).
Given two points, say A and B, you must be able to add, subtract,
and compare them. That is compute A + B, A - B, A <= B, and A >= B. You
may use the names "add", "subtract", "greaterThan", and "lessThan" rather than
the symbols "+", "-", "<=", ">=". You need to compute the distance
between A and B. Finally, you need a print operation that will print a
representation of the point on a stream. That is if A has x coordinate of 5 and
y coordinate of 11, you need to print on the stream "(5,11)".
2) Implement and test a Rectangle class. Instances of the rectangle class
represent a point in a two dimension coordinate system. A rectangle can be
specified by giving the points in the upper left corner and lower right corner
of the rectangle (see diagram below).
You must implement the following operations on a rectangle:
- Create a rectangle.
- Print a rectangle on a stream, (that is print the four corners of the
rectangle on a stream)
- Given a point and a rectangle determine if the point is inside the
rectangle,
- Given two rectangles determine if they intersect,
- Given a rectangle return an array containing the four points that
represent the corners of the rectangle
Note: printing the point and
rectangle on the screen will come later.
Two separate files, header and implementation, are required for each class. You
need a program that tests the two classes. The classes need to be compiled. The
binaries for the classes need to be linked to the test program. That is you
are not allowed to compile the classes and the test program as one file. You
need a make file or its equivalent that will compile the classes and the test
program. Turn in the classes, test program, make file, and output from the program.
