Description
the program needs to find the distance (farthest closest and the area details provided) between the point in Asn05.txt. can you write the codes for the buttons as it asked in asn05.pdf using c# visual studio? the program has the headers in the uploaded file (ASn05.zip)?
Asn05.txt
1, 1 2.4, 3.7 20, 43 46, 3 9, 33 -12, 5 -25, 5.9 -49, 42 -7, 7.4 -2.3, 37 6.7, -34 6.4, -3 45, -42 26, -21 10, -23 -12, -12 -35, -21 -37, -45 -10, -12 -25, -42

Assignment 5
2-D Arrays
Assigned: February 18, 2019
Due: March 6, 2019
This assignment will be done as a Windows Forms application. The form has been created for
you and you should begin by downloading Asn5Form.zip from the web site. Unzip this file and
use Visual Studio to open it as a project by double clicking on the solution file name. If you run
the program you will get a screen similar to that shown in Figure 1 below.
Click on the Load button to get a dialog box which will allow you to load Asn5.txt. This file is
in the project folder under bin/Debug. Selecting the file causes it to be loaded into a twodimensional array named dataPoints. This array holds up to 20 points where dataPoints[i, 0]
holds the x value for point i and dataPoints[i, 1] holds the y value for point i. All points are in
Cartesian coordinates.
The code behind the Load button has been written for you. For this assignment you must write
the code behind the other four buttons.

Button
Farthest from origin
Closest to origin
Smallest Triangle
Largest Triangle
Function
Displays the distance of the point that is farthest from the origin.
Displays the distance of the point that is closest to the origin.
Displays the area of smallest triangle that can be formed from the
points.
Displays the area of the largest triangle than can be formed from
the points
The distance between any point x1, y1 and the origin is given by
distance = x12 + y12
To compute the area of a triangle use the formula:
Area = s(s − a )(s − b)(s − c)
where s = (a + b + c) / 2 and a, b, and c are the lengths of the three sides of the triangle.
To calculate the length of the sides you can use the distance formula:
Distance = ( x1 − x2 ) 2 + ( y1 − y 2 ) 2
where x1 , y1 are the coordinates of one point and x 2 , y 2 is the coordinates of the second point.
Your program must be organized in modular fashion using methods. At a minimum you must
have one method to calculate the distance and a second to calculate the area.
Turn in a zipped project file. Name your zipped file Asn05XXX.zip where XXX are your three
initials. Upload your zipped project file to \\cecsfp01\users\everyone\Engr123
