Requriements

Program must compile with both -Wall and -Werror options enabled

Submit only the files requested

Use doubles to store real numbers

Print all doubles to 2 decimal points unless stated otherwise

Restrictions

No global variables may be used

Your main function may only declare variables and call other functions

Description

Write a program called perimeter.c that find the perimeter of an arbitrary shape. Your program will be provided a binary file that contains the vertices of the shape and your program should print out the premiter of the given shape.

Additional Details

You MUST use a struct in your solution

I recommend have a Point struct

The name of the binary file will passed as a command line parameter

The binary file contains only integers

The first integer is the number of points in the file

The remaining integers are points representing the vertices of the shape

There is an edge between each adjacent point and between the last point and the first point

There are at least 3 points in each file

The perimeter of a polygon is the sum of the lengths of all of its edges

If you really look at the the points in the file you will see that they don't actually represent convex polygons but treat them like the files like they do

Examples

User input has been underlined to help you differentiate what is user input and what is program output.

Hints

If you are curious about what is in the file you can use the binaryinteger printing program we wrote in class.

Examples

In this example assume that the file example.txt contained the following values in binary. I'm displaying the file as text below to help you get an understanding of what the file looks like but remember the file is in binary with no spaces between any of the values.

Example 1

3 287 422 283 -981 781 647

./perimeter.out example.txt

The perimeter is 3648.30
