A 2-dimensional 3x3 array of ints, has been created and assigned to tictactoe. Write an expression whose value is true if the elements of the diagonal that includes the first element of the first row are all equal.

Following are the expression of the given statement.

tictactoe[0][0] == tictactoe[1][0] && tictactoe[1][0] == tictactoe[2][0]

Explanation:

In the following scenario, there is the two dimensional or matrix array of integer data type 'tictactoe' which has a total of nine elements then, after that we have to define the diagonal of the array variable which comprises the very 1st element of the 1st row are equal. So, the following expressions are true according to the scenario.

the answer is you.
