Using C# Program Language

I have a bag of coins. Design a class that can sort and count coins according to their size. The class should also contain the methods that display the tallies for each kind of coin and the total amount of money in the bag. There may be foreign coins mixed in with the normal coins. These coins should be tallied but not used to calculate the total cash.

These are the diameters of US coins.

QUARTER

24 mm

DIME

18 mm

NICKEL

21 mm

PENNY

19 mm

We will simulate the bag of coins using an array of 30 integers;

The simplest solution is to use switch() construct to select and tally the different coins.

Declare the size of each coin as private constant in your BagOfCoin class.

Class Design: You may add any additional local variables and methods to implement the logic of your solution.

Class Name: BagOfCoins

Private data members:

quarters

int

counter for quarters in the bag

dimes

int

counter for dimes in the bag

nickels

int

counter for nickels in the bag

pennies

int

counter for of pennies in the bag

foreign

int

counter for foreign coins in the bag

public methods:   **There is NO initialization constrictor. No Properties required.

BagOfCoins

default constructor. Set all the counters to zero.

SortCoinTally

void

(int coin)->parameter list

takes a coin argument and sorts and tallies respectively

if the coin matches coin type then increment the coin counter

ToString

override string

Display the coin tallies and total amount

CalculateTotal

decimal

Calculate and return total amount

In your program.cs, create an array of 30 integers with initialization list. Use the following data to test your class.

const int SIZE = 30;

int [ ] bagCoins = new int [SIZE]   
                   {24,18,21,20,19,24,18,21,20,19,24,18,21,19,24,18,23,21,19,24,18,21,19,24,18,21,30,32,24,26}

QUARTER

24 mm

DIME

18 mm

NICKEL

21 mm

PENNY

19 mm
