You just have a small formatting error in the total price. If i order 10 sodas at $2.98, it shows $29.8 instead of $29.80 . Would be cool if the program gave a running total of what was purchased so far, in addition to the final total.
I took out the system commands like system("cls") cause it's not supported on linux (many online interpreters like the one I linked are based on linux), and system("pause") cause it has no place in a method other than main(), and also it's not good practice -- if you're debugging , set a breakpoint at the last closing bracket of main() so that the console doesn't go away. If you're in 'release' mode, then you should be running the program from a console and not from within an IDE like visual studio, so there's no need to try to save console from disappearing.
