What will be the output of this program?

#1

#include
#include
using namespace std;
int main()
{
int arr[5] = { 4, 5, 1, 0, 1 };
sort( arr, arr+5 );
cout<< lower_bound( arr, arr+5, 3 ) - arr <<endl;
return 0;
}
since 3 is not present in array

#2

lower bound gives you the pointer that is greater than or equal to the number.
So it will point at 4.
