Answer 1

You should've made a separate binary search function if you want to return item index.

But here you do the search inside main() so issuing a `return` will terminate the program, no matter what value you return.

I would first add a condition to check where <ele> is either less than a[0] or greater than a[n - 1]. In which case the search should not be performed at all because <ele> obviously is not in array. You can add this conditional after the array is sorted, but before search begins.

Comment line 41, 47, 48, 52, 53.

return 0; at line 56, you're in main().

Answer 2

It is because you are returning before printing. Change it like below.

if(ele == a[mid])
{
printf("\nvalue is ind at position %d \n",mid);
return mid;
break;
}
