Introduction

Following code demonstrates how to initialize an array of pointer to an int array.

#include <stdio.h>
int main()
{
    int *cmd[] = {
        (int []){0x1, 0x2, 0x3},
        (int []){0x4, 0x5, 0x6, 0x7},
    };

    printf("%d %d\n", cmd[0][1], cmd[1][2]);
}

See the differences with the following code?

#include <stdio.h>
int main()
{
    int cmd[2][4] = {
        {0x1, 0x2, 0x3},
        {0x4, 0x5, 0x6, 0x7},
    };

    printf("%d %d\n", cmd[0][1], cmd[1][2]);
}

It is two dimensions array initialization.
