Nope - it'll crash - there is not enough space in b to store both
strings...it shouldn't even compile because "This is" is
a const string and b isn't - the first argument of strcat can't
be a const string).

How about:

   char b [ 100 ] ;
   strcpy ( b, "This is" ) ;
   strcat ( b, " a test" ) ;
   printf ( "%s", b ) ;

....would work much better.
