                 You will get the following output:
                 Enter number of rows : 2
                 Enter number of columns : 2
                 Enter a number : 1
                 Enter a number : 2
                 Enter a number : 3
                 Enter a number : 4
                 Sum of row 1 : 3
                 Sum of row 2 : 7
