Question 5

Consider the following C function.

               void convert (int n) {
                       if (n < 0)
                          printf ("%d", n);
                       else {
                          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?

A

B
It will not print anything and will not terminate.
C
It will print the binary representation of n and terminate.
D
