declaring a two dimensional array in c code example

Example 1: how to declare multidimensional array in c

int a[3][4] = {  
   {0, 1, 2, 3} ,   /*  initializers for row indexed by 0 */
   {4, 5, 6, 7} ,   /*  initializers for row indexed by 1 */
   {8, 9, 10, 11}   /*  initializers for row indexed by 2 */
};

Example 2: 2D Array In C

// Array of size n * m, where n may not equal m
for(j = 0; j < n; j++)
{
    for(i = 0; i < m; i++)
    {  
        array[i][j] = 0;
    }
}
