More newbie questions

I have a 2d array and I want to print it using foreach. How do I do that?

[Volte]

A standard

Dim i As Integer

For Each i In multiDimArray
Next

will do it. I'm not totally sure what order it traverses it

(which dimension increments first in the loop), but I'm sure you

can figure that out.

[Morpheus]

Well that is VB code isn't it?

 

The array looks something like this. {{0,0}, {0,1}, {0,2}, {0,3}, {0,4}, {1,0}...........{4,4}

 

 

and it should look like this on the consolewindow:

 

0,0 0,1 0,2 0,3 0,4

1,0 1,1 1,2 1,3 1,4

 

and so on

[Volte]

Heh, sorry, I didn't realize this is the C# forum. In C# it would be

like this:

foreach(int i in theArray) {

}

[Morpheus]

Yes that's how far I got, but I can't get it to look the way I want it to. Someone told med that I had to use GetLength().

[Volte]

You know, you can always not use foreach; it may be more

appropriate, in this case, to use a standard for loop.

int i,j;
for (i=0;i<=myArray.GetLength();i++) 
 {
   for (j=0;j<=myArray.GetLength();j++)
   {                              
     // use myArray[i,j] to output the data
   }
 }

[Morpheus]

Yes that would be really nice :) but I have to use foreach, school assignement ya know.

[Volte]

Oh. Well, I really don't know what to tell you. foreach can easily

get the data, but I have no idea how to get it out in the order that

you want it. Sorry. :-\

[Morpheus]

Thank you anyway

[Nerseus]

If it's a school assignment shouldn't you be figuring this out on your own? :p

Why would you use foreach to traverse a 2-dimensional array?

 

Just curious. I assume your assignment gives some kind of reason. Perhaps I'm assuming too much :)

[Volte]

Perhaps it is a trick question, and your instructor wants you to say

"why?" :p

[Morpheus]

Nope no reason why and some friends have made it. Well assignement was a bad word to use, it's more like an excersice and we can use help from other people. There is a big difference between ripping code and getting help.

Done!

 

int[][] mul;

mul=new int[4][];

mul[0] = new int[5] {0,1,2,3,4};
mul[1] = new int[5] {0,1,2,3,4};
mul[2] = new int[5] {0,1,2,3,4};
mul[3] = new int[5] {0,1,2,3,4};
		
int counter=0;

foreach(int[] j in mul)
{
   foreach(int i in j)
   {
       Console.Write("{0},{1} ",counter,i);
   }
   
   Console.WriteLine();
   counter++;

}
