A triangle is equilateral if all three sides are equal, isosceles if any two (but no more than two) sides are equal, and scalene if no two sides are equal. A triangle will be inputted by the user by stating the three sides. The program should classify the triangle, and keep count of the number of each type of triangle.

In particular, for each iteration, first obtains the measurements of a triangle from the user. The prompt should be:

Please enter the three sides of the triangle on separate lines. Enter '-1' to quit. This should be followed by the classification of the triangle, such as:

25

5

25

The triangle is isosceles.

When the user terminates input (by entering a '-1', print out the following summary:

End of Processing.

The number of equilateral triangles was XX

The number of isosceles triangles was XX

The number of scalene triangles was XX

Structured programming must be used. In particular,

(1) Use a subprogram to prompt and obtain all the input for a single triangle from a user.

(2) Use a subprogram to determine the type of triangle based on the user input, and to update your running totals of each triangle type.

Use a pre-test loop for your processing in Main (with a priming read). Build both a C# and Visual basic Program.

Run them both using the following data for the triangle data to enter (each value on a separate line):

10.1 5 10.1

10 5.23 15

4 4 4

5.2 10 10

20.2 20.2 4.1

3 4 5

 Print the source code for each program version on a separate page, and attach the output using screen capture.

NOTE:

1. Terminate the use-input portion of the program ONLY if user enters -1 for the first side. A -1 for side 2 or side 3 should not terminate the user input.

2. You do not need to check for negative values for a triangle side. Assume all sides entered are positive values (unless the first side is a -1 to end).

3. Assume the sides entered are for an actual triangle

4. Do NOT use/change global variables - use parameter-passing
