for i = 0 to 3
.. for j = 0 to 2
.... print stupidarray[ I ][ j ]
.. println
no?
argh. can't get the indentation working
Being a developer for 15+ years...you have NO IDEA what a 2d array is. What everyone has said is a 2d array is a 2d array. What BlueFlamme input is a 2d array.

I'm not advanced programmer or anything...but wasn't what stan394 posted a 2-D array? I can't see why it isn't. I've only taken intro c++ and done a lot of game scripting so don't take what I'm saying as some master level programming knowledge here.
And "use the compare function"? What does that mean...does that even do the sorting? Isn't that just a piece of the code you might use to sort it?
This almost sounds like a question like "Whats the best way to build a boat?". Without any other specifics or constraints it seems like the only answer you could offer is more of an opinion then a fact.

Actually I'd say the above is not how I would represent the original list. Above would be
3 1 6
5 3 7
To me. That sort of visualization is typical in academic discussions of arrays. In some languages it will actually be accurate, beacuse 2d arrays are really just arrays of arrays, so each row represents an array. In other languages it would look like this because it's all stored in consecutive memory:
3 1 6 5 3 7
May I suggest you pick up a remedial first year college book that includes a chapter in programming arrays. I've taught this stuff, in a university, with a senior professor and a dept chair checking my work... neither of them found flaws in my understanding of two dimensional arrays.
Ok, I get that if the elements are not discrete, it's one dimensional, but how could i be 4 dimensional? Engineering major here, so I see it as 2 dimensions, (x,y) four dimensions would be (x,y,z,t) or (x,y,z,z-not) etc. How does that array have 4??
It it just in the vizualiation imo. If you consider the first array as a column and the second array as the row then you can print out the rows followed by an endl with some code like the following:
for(k = 0, k <2, i++){
for(j = 0, j < 3, j++){
cout<<stupidarray[j][k]<<' ';
}
cout<<endl;
}
would yield the original array he proposed. Yeah, i screwed up the typical ordering of row then column, just view it as similar to a poetic license for coding. And I put a ... in there to represent the other two columns that I didn't type up to shorten the post.
Hello ignoramus, read my post. I didn't say what he presented was NOT a 2d array. I was referring to the printed example earlier.
stan's example of a 2d array is correct.. It's a int[3][4] array..
I'm assuming the interviewer meant to ask what's a method that can be used in OO programming to help you sort an object? You'd use the compare method or whatever available method to compare one object to another. The way the question is phrased makes it horribly hard to understand what's going on.

Edit: Wait I see. Its been awhile....

In some languages you can write code inside of an object that defines how to compare it to another object of the same type (or different type). Then when something requests a sort of an array or list of those objects, the function that is used to do the actual sort will do its sorting algorithm and use the function you wrote to determine whether object1 > object2.
Thank you for kind and very accurate reply. You have summarized my thoughts, what I attempted to convey, etc. without doing so condescendingly.
This is all I meant to say. Don't know why it incited such a riot. Guess a lot of people have it out for me.
Yep. The interviewers question was terribly ambiguous and her answer was only one element of what would have been the final solution. I would question whether or not she could actually accomplish it herself, start to finish.
"Well sh*t... I called 'compare()', but all I got was this stupid useless int and nothing is sorted WTF"
Hello retard. Read your earlier posts where you have NO IDEA WHAT A 2D ARRAY IS. I guess reading the first quote in the post would suffice as well. Hey I've got a $1000 cup of coffee for sale. You not listening to the people in the thread is like people not listening to your very good opinion on coffee.
I don't think anyone has it out for you. Your condescending attitude certainly doesn't help, but the fact is you are wrong. It is a 2-dimensional array and most first year programming students could tell you that.
