So im making a menu for a project and i havnt really understood this array thing.. how do i make it so it says like: " What you want to add? "
and then its like "-ITEM- Has successfully been added!" and then it does the same 4 times till you've reached up to 4 items? I have to use this Array String for this one and i really need help on this part.

note that this is on my 5th menu choice under case 5 where i want this to happen.

thanks!

What I have tried:

case 5:
                       Console.WriteLine("\t You got room for 4 more items in this compartment, what would you like to add??");

                       string[] outercompartment = new string[4];
                       outercompartment[0] = "";
                       outercompartment[1] = "";
                       outercompartment[2] = "";
                       outercompartment[3] = "";
                      foreach(string stuff in outercompartment)
                       {
                           Console.WriteLine(stuff);
                       }

                       break;

You write a for loop to get the data.

yeah like the whole program has a loop, but i need the right stuff in this praticular menuchoice?

How would I know? I only know what you have told us about your homework assignment. And for what you have told us, you write a for loop to get the data to put in your string array.

First you must read in the four things to be done. That can be done in a loop. You could also add a test to allow fewer than four items (something like reading an empty line). I'd also suggest that you use a List < string > rather than an array. Lists are much more easily manipulated. So after you read in what the user wants to do, then you process those things. If you have further questions, reply to this comment.

yeah i've also used the List stuff, on another menuchoice, the whole project is done when i have the Array, since its a part of the assignment, but im stuck and dont realy understand how i do this, all i find is about Doing this with INT instead of String

gggustafson 15-May-17 15:36pm

I don't follow what you mean by "with int instead of string." Both are primitive types in C# so what you can do with int you can do with string (of course not mathematical stuff). Somewhere in your case 5 you need to read in things to do. Where do you do that? Show me some code.

FluzzyG 15-May-17 15:38pm

I dont do that anywhere, what i typed as code in my question is what my case 5 is at now, but its completely wrong , i feel like im just mixing stuff together and missing something really simple

gggustafson 15-May-17 15:47pm

Slow down. Don't get frustrated. So now you are processing case 5 of a switch statement. It would appear that you want to collect things that the user wants to do. There is really a simple way to do that using Console.Write and Console.ReadLn. All you do is perform a series of ConsoleWriteln that display a number followed by an action. At the end of displaying the four items, ask the user which item he wants to perform. When the user responds perform the action. After you perform the user's desired action, redisplay the list of indices and actions (now one shorter) and again read what item he wants to perform. Continue this until either there are no more actions or the user indicates he's finished (by say entering an empty response).

this is my case 5

case 5:
Console.WriteLine("\t You got room for 4 more items in this compartment, what would you like to add??");
Console.Writeline("Add: ");
string[] outercompartment = new string[4];
outercompartment[0] = "";
outercompartment[1] = "";
outercompartment[2] = "";
outercompartment[3] = "";

Console.WriteLine("you added: "+ outercompartment);

break;

But im missing something somewhere and i dont really get what more i need.

I see that from your question. But all that code does is write the message "You got room for 4 more items in this compartment, what would you like to add??" followed by the message "Add:" to the console (monitor); then creates a string array of four empty items; and finally displays the message "you added..." (by the way in a form that does not display the items in the array!). So what were you expecting?

Someone deleted your code. Let's take this discussion offline. Send your code to me at gggustafson at gmail dot com.

Have you received a usable response to your question. Someone closed your question (I don't know when) and I had to have it reopened. Sorry about that. Some Code Project members don't seem to understand. Anyway, I'm still here. Let me know.
