running total issues

Ghostman513 (12)
my code is acting like a hydra... get rid of one problem, 2 more take its place. if i put in one order of each variable its fine but if i do any combo that leaves out one, it still displays that drink with some weird exponential number. no clue where to start anymore, but the total that displays the price is unaffected and the total that displays the number of drinks ordered is unaffected. help is greatly appreciated. once i can get the issue fixed i will be modify it to do this
case 'C':
case 'c':
cout << "Thank you. You have ordered the Coffee.\n" << endl;
coffee++;
break;

the code displayed is the most successful so far.

Initialize variables. Pay attention to warnings generated by the compiler.

Hi,

Can I ask you nicely not to start a new topic for the same problem :+) ?

I answered your problem yesterday, now cire has pretty much given the exact same answer today.

If there is something you don't understand, then say so. We can explain more.

i solved that issue... this is a new problem but still in the same area. and there was no warnings from the compiler. and now its fixed... now i feel like an idiot. it was initialize variables.

and there was no warnings from the compiler.


I am sure I answered that problem in your other Topic too.
