Cashier 1.0 is a C++ program that displays on the screen item codes with corresponding item description and price (at least 10 items). It asks the user to enter the code of the item purchased by a customer. Then, its description and price are displayed on the screen too. Also, it asks for the quantity of the particular item code entered. Consequently, it displays the total amount due. Then, it asks the user to tender the amount of cash of the customer. Finally, it displays the change and its breakdown.

Constraints:

When any one of the scenarios happens, the program should exit.
• The user enters item codes that are not available.
• The user types in quantity less than or equal to 0.
• The user inputs amount of cash less than the amount due.

Grading Criteria:

Program Correctness 80%
Ease of Use 20%

Sample Run:
Welcome to CS131xxx Mart!
Item Codes Description Price
100 Sweet ‘n Ripe Grapes 302.90
101 Crunchy Apples 52.20
… … …
109 Green Peas 25.75

Enter Code: 100
Sweet ‘n Ripe Grapes 302.90 Qty: 1

Total Due: 302.90
Cash: 1000.00
Change: 697.10

=========== CHANGE BREAKDOWN ===========

Where is your code? What is your question exactly?

I'd do something like the following:

void changeDue(double amt)
{
    double denomination[12];
    double amtRemaining; 
    int numberOfDenomination = 0;
   
    denomination[0] = 1000.0;
    denomination[1] = 500.0;
    denomination[2] = 200.0;
    denomination[3] = 100.0;
    denomination[4] = 50.0;
    denomination[5] = 20.0;
    denomination[6] = 10.0;
    denomination[7] = 5.0;
    denomination[8] = 1.0;
    denomination[9] = 0.25;
    denomination[10] = 0.10;
    denomination[11] = 0.05;


    amtRemaining = amt;
    for (int i=0; i<= 11;i++)
    {
        numberOfDenomination = amtRemaining / denomination[i];

        if (numberOfDenomination > 0)
        {
            amtRemaining = amtRemaining - (numberOfDenomination*denomination[i]);
			
            cout << denomination[i] << ": " << numberOfDenomination;
            cout  << "(" << amtRemaining << ")" << endl;
       }
 }

It doesn't quite work for amounts that end in say $0.55 though. Don't have time to look at it more right now. But it should give you some ideas on how you might continue.

its in c++ . . . the breakdown is the hardest part so i was tryin to make a program of it for my hw . . . but its kinda hard . . . ok for example . . . the change that the cashier is gon to give to the customer is lets say $1250 . . . in the breakdown it will say how many 1000 , 500, 200, 100, 50, 20, 10, 5, 1, 0.25, 0.10, 0.05 are there in the change . . .

This version should work.

void changeDue(float amt)
{
    float denomination[12];
    float amtRemaining; 
    int numberOfDenomination = 0;
   
    //put monetary denominations into array
    denomination[0] = 1000.0;
    denomination[1] = 500.0;
    denomination[2] = 200.0;
    denomination[3] = 100.0;
    denomination[4] = 50.0;
    denomination[5] = 20.0;
    denomination[6] = 10.0;
    denomination[7] = 5.0;
    denomination[8] = 1.0;
    denomination[9] = 0.25;
    denomination[10] = 0.10;

    //initialize amtRemaining to amt
    amtRemaining = amt;
    for (int i=0; i<= 11;i++)
    {
