Solution 1

And the issue is? Tried?

You need two for loops and then just get random numbers to add to each array element. Try out.

First, if you know the number of coulmns and rows and they are fixed it is not jagged, it is just 2 dimentional array.

second, this is actually easy, just see the sample code here (random range: 0, 1000)

C#

public static void Main(string[] atgs)
       {
           //row 1 12 18 19 158 147 145 147 155 15
           //row2 14 17 18 15 19 16 114 15 4

           const int rows = 768;
           const int columns = 9;
           int[,] ai = new int[rows, columns];

           Random r = new Random();

           for (int i = 0; i < rows; ++i)
           {
               for (int j = 0; j < columns; ++j)
               {
                   ai[i, j] = r.Next(0, 1000);
               }
           }


       }
