What could be the problem
Feb 28, 2015 at 12:37pm UTC
I have some problems about this one, example. I just entered an invalid input on the question "What's your order?" but it'll skip the default: cout.but then just show all lines the cout on the first letter for example a you just ordered sweet and sour, how many order,order again, then the last part is the else cout. how can I go straight to default cout when i input an invalid answer in "whats your order", then how to loop on order again (y/n), if you put invalid choice, please do revised my program. any help is appreciate, im just a newbie please just adjust on this topics, if else, loop, switch case only, no void or str or namespace we havent done it yet. and if you are in the 1st loop if you put invalid input it'll forever loop, btw, this is turbo c

A simple
goto statement would save you lines.. I like
goto very much but it should be used carefully.... Anyways here's the code
1#include<conio.h>
#include<iostream.h>
