IT 401 Assignment 4 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?
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.
