convert (n/2);
printf ("%d", n%2);
}
}
Which one of the following will happen when the function convert is called with any positive integer n as argument?
| It will print the binary representation of n in the reverse order and terminate. | |
| It will not print anything and will not terminate. | |
| It will print the binary representation of n and terminate. | |
| It will print the binary representation of n but will not terminate. |
