Looks pretty simple to me.

Use _itoa function to convert the integer to ASCII text. You might want to use _itot if you are working with 32-bit OS like Windows 95 or NT.

May be you would like to use ltoa (for long to ASCII), if you are working with one of the low-end OSs, as the size of the int is small in these systems and you need to use the above said value as long or unsigned int.

The conversion functions that guruprasad points out do work well.  Here's an alternative:

{
  char buffer[64];
  sprintf( buffer, "%ld", 123456 );
}

If using MFC, you could also use the CString::Format method.

How to do it with c++? Does stdlib.h include it?

yeah. you need to include <stdlib.h> in your source code to do that.
