how to write a double 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: double array in c

int disp[2][4] = {
    {10, 11, 12, 13},
    {14, 15, 16, 17}
};
