How do you write a java program in which the user will enter an amount of money as a decimal number and the program will compute how many pennies nickels dimes quarters ones fives tens twenties etc.?

Answer 1

Denomination values should be stored in an integer array where each value is in pennies. So $100 is 10000 pennies:

const array<int,10> value = {10000, 5000, 2000, 500, 100, 50, 25, 10, 5, 1};

Create a parallel array with the actual denominations:

const array<string,10> denomination = {"hundreds", "fifties", "twenties", "fives", "dollars", "half", "quarters", "dimes", "nickels", "cents"};

Start by multiplying the amount by 100 to determine the actual number of pennies. So $1.23 becomes 123 pennies. Store this value as an integer named pennies.

Now work your way through the denominations in sequence:

for (int index=0; index<value.size() && pennies; ++index)

{

int number=pennies/value[index];

if (number)

cout<<number<<' '<<denomination[index]<<endl;

pennies%=value[index];

}
