Q.15: How to convert a one-dimensional array to a two-dimensional array?

 Ans.: The user will input 1-D array along with the number of rows and columns. The method should convert this 1-D array to a 2-D array(matrix) of given row and column. We will create matrix row wise.

•  input: {1, 2, 3, 4, 5, 6} ,2 ,3

output: 1 2 3

4 5 6

internal static void SingleToMulti(int[] array, int row, int column)

{

int index = 0;

int[,] multi = new int[row, column];

for (int y = 0; y < row; y++)

{

for (int x = 0; x < column; x++)

{

multi[y, x] = array[index];

index++;

Console.Write(multi[y, x] + " ");

}

Console.WriteLine();

}

}
