What will be the output of the following C++ code?
#include <stdio.h>
#include <stdlib.h>
int compareints (const void * a, const void * b)
{
return ( *(int*)a - *(int*)b );
}
int values[] = { 50, 20, 60, 40, 10, 30 };
int main ()
{
int * p;
int key = 40;
qsort(values, 6, sizeof (int), compareints);
p = (int*) bsearch (&key, values, 6, sizeof (int), compareints);
if (p != NULL)
printf ("%d\n",*p);
return 0;
}
