Write the exact value printed to standard output stream by the following code fragment:

int foo(int const array[], unsigned long elem_cnt) {
  int val = array[0];
  for (unsigned long i = 1; i < elem_cnt; ++i) {
    val = (array[i] > val) ? array[i] : val;
  }
  return val;
}
int x[] = {10, -10, 20, -20, 30, -30};
printf("%i", foo(x, sizeof(x)/sizeof(x[0])));
