Question

C#

Goals:

Practice building a class

Use object oriented programming to solve a problem

Problem Description:

Create a Windows Console Application using the .NET Framework For this application you will be designing a program that allows

users to keep track of robot inventory. First, you will design a Robot class, and then

build an application that creates Robot objects.

Important formulas / relationships:

Before we begin designing robots, we should understand a few key electrical terms and

relationships.

Terms:

Voltage (V)

- The electrical potential between two points, measured in volts.

Current (I)

- The flow of electrons through a material, measured in amps.

Resistance (R)

- A measure of the restriction of current flow through a material,

measured in ohms.

Current = Voltage / Resistance

Power (P)

- The measure of electrical energy over time, measured in watts.

Power = Voltage * Current

Watt-Hours (Wh)

- A Measure of how much power could be supplied in 1 hour. A

typical AA battery has a voltage of 1.5 Volts, and a supply of 3.75 Watt-Hours. This

means a AA battery could supply 3.75 Watts of power for 1 hour, or 7.5 Watts of power

for 30 minutes.

Power supply length ( in hours ) = Total Watt-Hours / Power

Summary:

I = V / R

P = V * I

Time = Wh / P

1 AA Battery = 1.5 Volts, 3.75 Wh

Robot Class Details:

Add a

Robot

class to your project. Include all fields, properties, methods and

constructors to properly build a Robot object with the following attributes and behaviors:

Attributes:

ID (string value) -- must be a length of 4 or 5 characters

Number of AA Batteries (int value) -- must be between 2 and 6

Resistance (double value) -- can be any value greater than 0

Behaviors:

GetPower() -- returns the power, in Watts, of this robot.

GetRunTime() -- returns how long this robot will run, given its number of batteries

(!) Remember -- each AA battery can produce 3.75 Watt-Hours of energy

Summary() -- prints the ID, Number of Batteries, Power, and RunTime values of

this robot

NOTE: Protect your class against invalid values!

Main() Program Details:

In Main(), create a program that allows the user to to enter in robot information for a

number of robots, and then calculates and prints a robot summary report.

Prompt the user to enter in the number of robots they wish to build.

For each robot, Prompt for the robot’s ID, Number of AA Batteries, and

Resistance

After all robots have been entered, output the following:

How many total batteries are required for all the robots entered?

What is the average Power of all robots entered?

Which Robot ID has the longest runtime?

Print the Summary for all robots entered.

Hint: Use object’s built from the Robot class to solve these problems!

CODE:

I created 2 Classes, one is Program(Contains main method) and another Robot class
