How to initialize N dimensional arrays in C without using loop

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 wit

Answer 1

matrix[0][2] = matrix[0][1] = matrix[0][0] =
matrix[1][2] = matrix[1][1] = matrix[1][0] = 0;
matrix[2][2] = matrix[2][1] = matrix[2][0] = 1;

or

#include 
...
memset(matrix, 0, sizeof(matrix));
matrix[2][2] = matrix[2][1] = matrix[2][0] = 1;
