22C:31 Algorithms Programming Project: Additional Instructions
- As discussed in class, the format for the input file to your programming
The coordinates (x1, y1) specify the first point. Similarly
each of the other lines contain coordinates for a point in the input. The
x-coordinate and the y-coordinate are separated by white space.
For the regular part of the project, you may assume that the points are
specified in counter-clockwise order around the convex polygon that
For the first extra credit part of the project, you cannot assume any ordering
on the input points, but you may assume that they do form the vertices
of a convex polygon.
Your program does not have to do any error checking. It may assume that
the coordinates are in the range 0 through 400. As mentioned in the
project, it may assume that no three points are collinear. There might be
other assumptions that you make; make sure to mention these in your
- Your program, when executed, may or may not prompt the user for the name
of an input file. If your program does not prompt the user for the name of
an input file, make sure that your program is hardcoded to read from a
file called points.txt.
We will create a text file with this name for testing your program.
- It is possible that your program may run fine on some inputs, but not
on others. If you want to to demonstrate the correct running of your porgram,
you should include files named points1.txt, points2.txt,
etc., in your submission. Also, mention this in the documentation that you
submit. We will execute your program on the point sets you provide before
testing it on our point sets.
