Binary_search(_)

#1

#include
#include

using namespace std;

int main()
{

int n=10;
int arr[10]={1,2,3,5,40,6,8};

int key;
cin>>key;

bool val=binary_search(arr,arr+n,key);

if(val)
{
	cout<<"Present!";
}
else
{
	cout<<"Absent!";
}

return 0;

}

if i will put input as 40, it is giving wrong output, why is it so???

@CODER_JATIN for binary search to work array should be sorted
