IT 401 Assignment 4 | Complete Solution

Question One
a)    Consider the following 2-dimensional array. Write a code snippet that gives the number of columns in the third row.

int[][] counts =
    {
       { 0, 0, 1 },
       { 0, 1, 1, 2 },
       { 0, 0, 1, 4, 5 },
       { 0, 2 }
    };
b)    Write a code snippet, that defines a two-dimensional array of 200 rows and 100 columns of the type integer?
c)    Consider the following code snippet:

int[][] arr =
{
   { 13, 23, 33 },
   { 14, 24, 34 }
};
Write the appropriate statement to display the value 24 from the given array?
d)    Consider the following code snippet:

int[][] arr =
{
   { 11, 22, 33 },
   { 44, 55, 66 }
};
int val = arr[0][0] + arr[1][2];
System.out.println(val);
What is the output of the given code snippet on execution?

e)    Consider we a have the following two dimensional array

   { 1, 2, 3, 0 }
   { 4, 5, 6, 0 }
   { 0, 0, 0, 0 }

Write a code snippet to print the sum of the highlighted color numbers.
