- for (int i = 0; i < anArray.GetLength(0); i++)
Console.Write(anArray[0, i] + “\t”);
-for (int i = 0; i < anArray.GetLength(0); i++)
Console.Write(anArray[i, 0] + “\t”);
- for (int i = 0; i < anArray.GetLength(1); i++)

Answer #1

Solutin:

Following segment of code will display the first row of a two dimensional array anArray.

for (int i = 0; i < anArray.GetLength(1); i++)
Console.Write(anArray[0, i] + “\t”);

Explanation:

GetLength(i) returns the number of elements in the ith dimension. So for a two dimensional array GetLength(0) returns the number of rows and GetLength(1) returns the number of columns.

anArray[0,i] will print the first row elements , as i will vary from column 0 till the number of columns specified by GetLength(1).
