Given a two-dimensional array of integers named q, with 2 rows and 4 columns, write some code that puts a zero in every element of q. declare any variables needed to you.

By choosing a programming language such as Java, the codes that puts a zero in every element of the two-dimensional array, q can be as follows:

public class HelloWorld{     public static void main(String []args){                int q[][] = new int[2][4];                for(int i = 0; i < 2; i++)        {            for(int j = 0; j < 4; j++)            {                q[i][j] = 0;            }        }     }}

Explanation:

Line 5 -  Declare a variable q and specify two indices 2 and 4 within the square brackets. This will create an array with a size of 2 rows and 4 columns.Line 7 -  Write an outer for-loop that iterate through the rowsLine 9 -  Write an inner for-loop that iterate through the columnsLine 11 - Assign zero to the element of q at a specific index, i (current row number) and j (current column number). This line of code will run repeatedly and assign zero to q[0][0], q[0][1], q[0][2] q[1][0], q[1][1],q[1][3]

We can also verify our result by adding some codes (Lines 15 - 21) to print every element of q and check if all of the elements are set to zero:

public class HelloWorld{     public static void main(String []args){                int q[][] = new int[2][4];                for(int i = 0; i < 2; i++)        {            for(int j = 0; j < 4; j++)            {                q[i][j] = 0;            }        }                for(int i = 0; i < 2; i++)        {            for(int j = 0; j < 4; j++)            {                System.out.println(q[i][j]);            }        }     }}

We will see the Line 19 will print out zero for each element of q.
