Two Dimensional Array: These are arrays which represent data in the forms of rows and columns. Int [,]=new int[3,4]; Or Int[,] arr; Arr=new int[2,3]; We can identify each and every cell by using row and column index as following: Int [,] arr=new int[4,5]; Arr[0,0]=5; Arr[0,1]=10; We can use getlength method to find no. of rows and column as following: Arr.getlength(0) for Rows Arr.getlength(1) for columns Class tdarray { Static void main() { Int a=5; Int[,] arr=new int[4,5]; For( int i=0;i
