               if (i == 10)

                              printf ("\n%d is not present in the array.", key);

               else

                              printf ("%d is found in array at %d position.", key, i + 1);

};

Output

Input 1 element: 27
Input 2 element: 46
Input 3 element: 92
Input 4 element: 42
Input 5 element: 80
Input 6 element: 58
Input 7 element: 13
Input 8 element: 22
Input 9 element: 73
Input 10 element: 38

Input key: 80
80 is found in array at 5 position.
