COS 126 Exercise Set 6

Answers

These programming exercises are intended help review the material on recursion, pointers, and dynamic memory allocation. Do not turn in solutions.

1. Implement this version of itoa: char *itoa(int n, int b) returns a dynamically allocated null-terminated string giving the character representation of n in base b. The caller must deallocate the returned string. For example:

   char *s = itoa(875, 5);
   printf("%s\n", s);

   Prints 12001 and deallocates s.
