usage of multidimensional arrays

[malola123]

Hey,

I was practicing some c# concepts while i found this weird thing happening. I am basically creating a simple two dimensional array with 3 rows and 2 columns. Here is the code.

using System;

class Array
{
public static void Main()
{
int[,] myArray =
{

{ 2, 3 },
{ 4, 5 },
{ 6, 7 }
};
int x;
int y;

for (x = 0; x < 3; x++)
for (y = 0; y < 2; y++)
Console.WriteLine( myArray[x, y] + " ");

Console.WriteLine();

}
}

Everything seems fine, and once I debug it, there are no build errors. However, when the console results are shown the follwing is displayed:

2
3
4
5
6
7

It do not want this type of display. My preference is:

2,3
4,5
6,7

Can anyone show what im doing wrong. Please and thanks!!

I don't have access to the tools to check it atm, but I think what you want to do is this:

for (x = 0; x < 3; x++)
     Console.WriteLine( myArray[0, x] + ", " + myArray[1,x]);

I imagine you will have to convert the integers to strings.

Hope this helps,

Alex

Console.WriteLine( myArray[x, y] + " ");

This line is causing only one number to be displayed on a line.

try using Console.Write() instead.

This will give you what you want

int[,] myArray =
{
{2,3},
{4,5},
{6,7}
};
int x;
int y;

for (x = 0; x < 3; x++)
{
string line = string.Empty;

for (y = 0; y < 2; y++)
{
line += myArray[x, y].ToString() + ",";
}

line = line.Substring(0, line.Length - 1);
Console.WriteLine(line);
}

The problem was that you were just getting the value of the array originally at the spot and making it its own line. You need to construct a line based on the output format you wanted to get. This may not be ideal or optimized, but it does work and should give you the idea.
