To do this, you can first convert the input amount into cents:

$xx$.$xx $*100($cents$)$

$($Alternatively$,$ you can input $xx$.$xx as a string using the string library. You

can then read each character and convert it back into a number like $$$$10\mathrm{.}74$

would be dissected as $1,0,....$ Each character can be converted back to

numeric value by subtracting it from $0$ like $10$ becomes number $1.)$

You now have an integer number of pennies that need to be divided into $25,$

$10,5$ and single pennies. The coin designations are easily found by an

algorithm the uses the two operators $(/$ for int division$)$ and $(\%$ for remaining

amount$).$ The algorithm is shown below
