Question

How can I remove these warnings?

   char foo[10], msg2[100]; 
   int k;
   for (k = 0; foo[k] != NULL; k++) //comparison between pointer and integer
       msg2[k] = NULL; //assignment makes integer from pointer without a cast

Thanks.

   int k;
   for (k = 0; foo[k] != '\0'; k++)
       msg2[k] = '\0';

Assign an integer to an integer variable, instead of a pointer. NULL is a pointer. It is usually defined as:

((void *) 0)
