Re: food menu restaurant Dennis E White12-Feb-14 5:02 Dennis E White 12-Feb-14 5:02  have you tried identifying the views for this app?? this might help you in achieving what you are going after for the app and create/answer questions to help you further along. from what I am seeing so far I can envision at least 3 different views. one with the screen containing these two buttons you want and then a view that gets displayed for each button. since in processing is a collection of orders you will probably have an array of some sort. does all this information get sent to a server somewhere?? does the server store state of orders?? how do you talk to the server?? you really need to sit down and start asking yourself and your team (if you have one) a lot of questions about the app and what the problem is that you are trying to solve. you want something inspirational?? Functions JamieM9429-Jan-14 21:50 JamieM94 29-Jan-14 21:50  Hi, I'm fairly new to objective C and I'm just learning how to use functions. In the below function I understand what the first line does but then the statements below have me a bit confused can anyone explain it to me? Its the "theBudget->budget" bit I dont understand. Objective-C void spendDollars (budget* theBudget, double dollars) { theBudget->budget -= dollars; Thanks for your help in advance Re: Functions Richard MacCutchan29-Jan-14 22:21 Richard MacCutchan 29-Jan-14 22:21  This is standard C notation, and a fundamental construct of the language. If you don't understand it, then you really need to go back to basics and get yourself an introductory book. The first parameter (theBudget) in the function declaration is a pointer to a budget object (Class or Structure). In the first line of the function the program is subtracting the value of the dollars item from the budget member of the object. A rather poor use of names calling a member of the object by the same name as the object type. In fact I'm not sure that that would not produce a compiler error or warning.

I am a beginner and this is an example they are using in an introductory book to explain functions. Going off what you have said this is a pretty poor example which is probably why I'm getting a bit confused.Thanks for the help Re: Functions Richard MacCutchan30-Jan-14 0:45 Richard MacCutchan 30-Jan-14 0:45  You may like to see https://developer.apple.com/library/ios/documentation/Cocoa/Conceptual/ProgrammingWithObjectiveC/Introduction/Introduction.html[^].

Just curious about that. Maybe with qualification it would be clearer. Like it isn't 'valid' because it is a homework question and one should do ones own work? If so then 'valid' might not be the best word. Or perhaps because it isn't possible to do what the OP asked in Objective-C? Re: How to print a two dimensional array using one loop?

It looks valid to me. I am using the following definition (from google). valid: (of an argument or point) having a sound basis in logic or fact: reasonable or cogent.
