Question

I want to initalize a 3 x 3 matrix with first two rows as 0’s and last row as 1’s. I have declared a 2D array int matrix[3][3]

I want to initialize it without using loops as shown below

0 0 0
0 0 0
1 1 1

I would also like a solution for N dimiensional array

Answer 1

int matrix[3][3] = {
    { 0, 0, 0 },
    { 0, 0, 0 },
    { 1, 1, 1 }
};

Or, the more compact:

int matrix[3][3] = {
    [2] = { 1, 1, 1 }
};

The solution generalizes for N so long as N is fixed. If N is large, you can use mouviciel’s answer to this question.
