Description
Files to submit: perimeter.c
Time it took Matthew to Complete: 20 mins
-
All programs must compile without warnings when using the -Wall and -Werror options
-
Submit only the files requested
-
Do NOT submit folders or compressed files such as .zip, .rar, .tar, .targz, etc
-
-
Your program must match the output exactly to receive credit.
-
Make sure that all prompts and output match mine exactly.
-
Easiest way to do this is to copy and paste them
-
-
All input will be valid unless stated otherwise
-
Print all real numbers to two decimal places unless otherwise stated
-
The examples provided in the prompts do not represent all possible input you can receive.
-
All inputs in the examples in the prompt are underlined
-
You don’t have to make anything underlined it is just there to help you differentiate between what you are supposed to print and what is being given to your program
-
-
If you have questions please post them on Piazza
-
-
The points of the polygon will be stored in a file and this file will be passed on the command line arguments
-
The file itself will be a binary file containing integers
-
-
-
-
The first integer in the file is the number of points contained in the file
-
The remaining integers are the points, with the first integer being the x coordinate and the second integer being the y coordinate.
-
There is an edge between each adjacent point and between the first point and the last point
-
Each file contains at least 3 points
-
-
The perimeter of a polygon is the sum of the lengths of all of its edges
-
Use a double to store your perimeter and report the perimeter to the nearest 2 decimal points.
-
As an aside the example tests do not form actual polygons but assume that they do.
-
Example. Assume that there is a file called example.txt. It will store the following information but in binary form. This example is just to give you a visualization of the data.
