Exercise: Write a program that takes user input as a double value representing total in dollars and cents and outputs a report listing monteary equivalent in dollars, quarters, dimes, nickel and pennies.
Enter an amount in double (Eg: 11.56) : 11.56 Your amount 11.56 consists of : 11 dollars 2 quarters 0 dimes 1 nickels 1 pennies
Caution: One problem with the program is the loss of precision. Running the program for amount of 10.03, 10.03 * 100 to become 1002.9999999999. The program hence will output 10 dollars and 2 pennies. The program will need to re-written to take input in integers (say 1002 for 10.02 for instance).
