Postal Barcode Assignment

cpunkymonkey (6)
Hello! I would like assistance with the code below. My issue is that I do not know how to output the equivalent barcode for each digit of the zipcode. My code is only outputting the equivalent barcode for the first digit of 9. The zip code I am working with is 95014.
Would you be able to give me a hint as to what I need to add? I am a bit lost with user defined functions and just recently learned it in class but the lecture wasn't that great. Any help would be greatly appreciated, thank you!

Line 14: You call getzipcode passing zipcode by value. The zipcode variable at line 12 is never updated. You need to pass zipcode by reference.

Line 15: When you call printzipcode(), zipcode is still 0.

Hi @abstractionanon Thank you for responding! However, I do not understand. Why did it read the first digit of 9 if the zipcode is still 0?

I believe that's the correction digit.

@AbstractionAnon thank you for pointing that out.
