C++ Program - Easy

Instructions: To write a program that will calculate change for a sales purchase. The program should prompt for a sales price. Validate that the data entered is a number greater than 0. If the data entered is incorrect, display an error message and end the program. Next, prompt the user for the amount that the customer will pay to the cashier. Validate that this value is greater than or equal to the sales price. If it is not, display an error message and end the program. If the entry is correct, your program must calculate the amount of change to return to the user. Next, calculate what bills and coins that the the cashier needs to return to the customer. The fewest number of paper bills and coins should be returned. You can make change in many different combinations, however, the only correct implementation is the one that returns the fewest paper bills and coins. Display the number of each of the bills and coins. Here is a sample run of the program: Enter in a sales amount: $20.38 Enter in the amount the customer pays: $30.00 The change due back is $9.62 You should give the customer this change: 0 $100 bills 0 $50 bills 0 $20 bills 0 $10 bills 1 $5 bills 4 $1 bills 1 Half Dollars 0 Quarters 1 Dimes 0 Nickels 2 Pennies Because of the way arithmetic works with float variables, storing the monetary values as floats may cause some problems. For example, if you had a float variable that held 1.29 to represent $1.29 and you subtracted the .05 from it (to represent giving back a nickel) you would think that you would be left with exactly 1.24. Unfortunately, the computer might store that value or it might store 1.2399999 or 1.2400001 instead of exactly 1.24. These very small inconsistencies can cause a problem calculating the number of pennies to return. This needs to be done in the C++ programming language. Project due date is 9:00pm CST
