Here is recursive function. Identify the recursive case and the default case.

Question

```
void recursive( int i ) //a)
{
if ( i < 8 ) //b)
{
i++; //c)
recursive(i); //d)
cout << i << " "; //e)
}
}
//f) The base case is not explicitly listed. If you choose this answer,
// then you must explain what the base case is.
```

Answer 1

The recursive case is line d), where the call to recursive with a larger
value of i . The other answer is f). The base case is not explicitly listed.
Explanation: The base case is the “do nothing” alternative of the if statement,
which is !(i == 8). This corresponds to i>=8. If you call the function with
arg 9, the base case is 9.
