Answer:

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:

  1. public class HelloWorld{
  3.     public static void main(String []args){
  4.        
  5.        int q[][] = new int[2][4];
  6.        
  7.        for(int i = 0; i < 2; i++)
  8.        {
  9.            for(int j = 0; j < 4; j++)
  10.            {
  11.                q[i][j] = 0;
  12.            }
  13.        }
  14.     }
  15. }

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 rows
  • Line 9 -  Write an inner for-loop that iterate through the columns
  • Line 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:

  1. public class HelloWorld{
  3.     public static void main(String []args){
  4.        
  5.        int q[][] = new int[2][4];
  6.        
  7.        for(int i = 0; i < 2; i++)
  8.        {
  9.            for(int j = 0; j < 4; j++)
  10.            {
  11.                q[i][j] = 0;
  12.            }
  13.        }
  14.        
  15.        for(int i = 0; i < 2; i++)
  16.        {
  17.            for(int j = 0; j < 4; j++)
  18.            {
  19.                System.out.println(q[i][j]);
  20.            }
  21.        }
  22.     }
  23. }

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