Array and class - Can't add numeric values

[jlpurnell]

So, I'm writing the program to be a simulated soda machine, but I can't get a "SOLD OUT" to display when the count reaches zero and I can't get the $1.50 soda total purchases to add correctly.

Thank you to all that read my code and help!

Please edit your code using code blocks, and if you could for the sake of readability put some tabbing in as well (The second is just a minor suggestion).

Sorry, that's how it copy/pasted.

[jlpurnell]

I don't know how to make it look better. :(

this will show you how to use code tags.

if (choice = 5) should be if (choice == 5) this is in your buy drink function

Thank you Yanson!
