atoi

I don't understand the results of the following C code.

main()
{
   char s[] = "AAA";
   advanceString(s);
}

void advanceString(p[3])
{
     int val = atoi(p);
     printf("The atoi val is %d\n",val);
}

Here the atoi val is shown as 0. But I could not figure out the exact reason. As per my understanding, it should be the summation of decimal equivalent of each values in the array.? Please correct me if I am wrong.
