# Issue with my program.... counting coins • ### Question

• I wrote a simple program to count US coins and tell me how much change I have.

http://smallbasic.com/program/?RCP391

```TextWindow.WriteLine("Hello. I will count your money.")

TextWindow.WriteLine("How many dollar coins do you have?")

TextWindow.WriteLine("How many half dollars do you have?")

TextWindow.WriteLine("How many quarters do you have?")

TextWindow.WriteLine("How many dimes do you have?")

TextWindow.WriteLine("How many nickels do you have?")

TextWindow.WriteLine("How many pennies do you have?")

cents = (dollarcoins * 100) + (halfdollars * 50) + (qaurters * 25) + (dimes * 10) + (nickels * 5) + pennies

TextWindow.WriteLine("You have " + cents + "¢ in coins according to the amounts you entered.")

```
I've was using sample numbers to try this out. Here they are:
dollar coins -- 1
half dollars -- 2
quarters -- 3
dimes -- 28
nickels -- 25
pennies -- 95
This is a total of 775¢ (I haven't figure out how to make this appear in dollars\$)
I have checked this total several times.

Everytime I run this program with these numbers, it gives me a total of 700¢

I cannot find my problem, but if any of you could check this and try to find my mistake, that would be great!

Thank you!!!

• I has found the bug.

You have this line

but in the line where you calculate the total, you have mispelled quarters:

cents = (dollarcoins * 100) + (halfdollars * 50) + (qaurters * 25) + (dimes * 10) + (nickels * 5) + pennies

The value of the variable qaurters is 0, so there's your missing 75 cents.

• Maybe SmallBasic v0.5 should have a 'few-used variable' checker that show variables that are used very few time, or that are never setted in the program using MyVar = ...

Print(MyVar)
DoSomethingElse(MyVar)

would show the warning : "The MyVar variable is never set in your program. Consider removing this variable by using "" or another variable."

• One way to format your money is using Math.Floor and Math.Remainder

Math.Floor(cents / 100)

Math.Remainder(cents, 100)

TextWindow.WriteLine("You have " + Math.Floor(cents / 100) + " dollars and " + Math.Remainder(cents, 100) + "¢ in coins according to the amounts you entered.")
