Use sprintf.

ALternately, you could do something like this (probably not the most efficient approach, but fairly straightforward:

Code
  1. #define MAXDIGITS ... // maximum number of digits that an int type can represent. 

    2. 

  2.                       // Will vary by implementation (16-bit vs. 32-bit vs. 64-bit)

    3. 

  3.  

    4. 

  4. /**

    5. 

  5.  * Precondition: target points to a writable buffer large enough to hold the result

    6. 

  6.  */'0', '1', '2', '3', '4', 

    7. 

  7.                     '5', '6', '7', '8', '9''-'

Oh for Pete's sake, what's the point of having an "insert code" option if it munges the code beyond all recognition? Seriously, for a site geared towards programming questions, the support for actually *posting code* is pretty poor.
