2 3 4 8 9 10 Indexing starts from 0. You have row 0 and row 1. And column 0, 1, 2. So [0][2] -> means row 0 and column 2. Which is 4.

Are you sure it was cout << [0][2]; ? I got error message trying to run that snippet ... However, it should output 4 if you wrote cout << x[0][2];

Int x[2][3]={{2,3,4},{8,9,10}} Its like this: 2 3 4 8 9 10 You have 2 rows and 3 column. First row index 0 : ( [0]--> 2 3 4) and the second row index 1 ([1]--> 8 9 10) First column index 0: ( [0]--> 2 8) and the second column index 1 ([1]--> 3 9) and the third column index 2 ([1]-->4 10) First element in row 0 is x[0][0] = 2. Second element in row 0 is x[0][1] = 3. Third element in row 0 is x[0][2] = 4. First element in row 1 is x[1][0] = 8. Second element in row 1 is x[0][1] = 9. Third element in row 1 is x[0][2] = 10. X[0][2] means the third element in the first row, in this eg is 4.
