This is the error message i keep getting and i dont know what it means

$ c++ 1.cpp
Undefined first referenced
symbol in file
purchased(int &, int &, int &, int &, int &, int &)/var/tmp/ccYQ5XO1.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status
$

I don't know ANYTHING about C++ but I noticed a typo in this line "purchase(brand, quanitity, coke, pepsi, dry, hires);" there's an extra i in quantity.

>your code is crap
No argument there.

>haven you ever consider using header files and making it into objects
Using classes and objects isn't always the optimum solution, and for small programs, it may not be practical to use multiple files. I disagree with both of your reasons for calling the code crap.

>either you are stupid, or stupid
I hate to break it to you, but I'm not the one that seems stupid. :lol:

>but classes and object are always the best solution for any program
Prove it. Show me every program in existence and how objects are the best solution.

>the codes looks alot better
That's an opinion, and doesn't work well as an argument in favor of your preferred methodology.

>if you can make it work i will agreee with everything you said
If I can fix half a dozen typos, you'll agree with everything I said? Wow, you're a cheap date.

am sorry, just ignore me, but i am going to try and make the program work, thanks for being understanding

I agree, how about a struct instead of passing about 5 or 6 parameters. That way all you have to do is pass a single object.

Fix your typos too and your all set!

this is my new code but i keep getting errors in the purchase() and sell() i can input what i need but it doesnt do like the others and keep going until i quit the program

Look at the condition for your loops, then look at the body of the loops and see how the condition could never change. You've written a bunch of infinite loops.
