Write a C++ program to implement a cash register program

Write a C++ program to implement a cash register program. The program will
prompt the user to enter an amount equal to the amount of a purchase. The
program will also prompt the user to enter an amount tendered. The program
will read values for each item.

The program will determine if the amount tendered was sufficient. If it
was not, the program will calculate the amount the customer is short in
his payment and print
"The Amount tendered was ****. The amount of the purchase was ****.
Please tender the additional amount of ***** ."

If the amount tendered was sufficient, the program will print
"The Amount tendered was ****. The amount of the purchase was ****.
The total amount of change to be returned to the customer is ******."

If the total amount to be returned is greater than zero, the program will
print the non-zero amount of each denomination to be returned.
Denominations will be in twenties, tens, fives, ones, quarters, dimes,
nickels, and pennies.

For example,

If the purchase price is $3.37 and the amount tendered is $50.00 the
program should print:

The Amount tendered was $ 50.00. The amount of the purchase was $ 3.37.
The total amount of change to be returned to the customer is $ 46.63.
This will be returned as
Twenties: 2
Fives: 1
Ones: 1
Quarters: 2
Dimes: 1
Pennies: 3

CSCI 135 Students:

You must have a class called Change which has one integer private members for the number of each denomination:

private:

numTwenties
numTens
numFives
numOnes
numQuarters
numDimes
numPennies

One functionality should be written to show the number of each denumination.

One functionality should be written to set each number to 0.

And another functionality that takes a parameter placeholder double which represents the amount to make
change for, and fills the number of each denomination correctly.

Here is a start for you:

CPP / C++ / C Code:

// Change.h
class Change
{ private:
    int numTwenties;
    int numTens;
    int numFives;
    int numOnes;
    int numQuarters;
    int numDimes;
    int numNickels;
    int numPennies; 
    
  public:
    Change();
    Change( double dollars );
    Change( int twenties, int tens, int fives, int ones, int quarters, int dimes, int nickels, int pennies );
    
    double AmountInDollars();
    void SetAmount( double dollars );

   // I would probably add a method for setting/getting each of the twenties/tens/etc.
    void SetTwenties( int twenties );
    int GetTwenties();
};

CPP / C++ / C Code:

// Change.cpp
// Default constructor
Change::Change()
{ SetAmount( 0.00 );
}

Change::Change( double dollars )
{  SetAmount( dollars );
}

void SetAmount( double dollars )
{ numTwenties = 0;
  numTens = 0;
  numFives = 0;
  numOnes = 0;
  numQuarters = 0;
  numDimes = 0;
  numNickels = 0;
  numPennies = 0;

  while( dollars >= 20.00 )
  { numTwenties++;
    dollars -= 20.00;
  }
  while( dollars >= 10.00 )
  { numTens++;
    dollars -= 10.00;
  }
  while( dollars >= 5.00 )
  { numFives++;
    dollars -= 5.00;
  }
  while( dollars >= 1.00 )
  { numOnes++;
    dollars -= 1.00;
  }
  while( dollars >= 0.25 )
  { numQuarters++;
    dollars -= 0.25;
  }
  while( dollars >= 0.10 )
  { numDimes++;
    dollars -= 0.10;
  }
  while( dollars >= 0.05 )
  { numNickels++;
    dollars -= 0.05;
  }
  while( dollars >= 0.01 )
  { numPennies++;
    dollars -= 0.01;
  }
}

double AmountInDollars()
{ return 20.0*numTwenties + 10.0*numTens + 5.0*numFives + numOnes + 0.25*numQuarters + 0.1*numDimes + 0.05*numNickels + 0.01*numPennies;
}
