Hi,

   The following program demonstrates an attempt to circumvent the const
specifier:

----------------------------------------
void foo ( const int *f ) {
   int *foo = f;
   *foo = 100;  // defeat const!
}

main () {
   int foobar;
   int *bar = &foobar;
   foo ( bar );
}
----------------------------------------

g++ doesn't complain about this, whereas CC retorts:

----------------------------------------
CC  test.C:
"test.C", line 6: error: bad initializer type const int * for foo ( int * expected)
1 error
----------------------------------------

This seems like a reasonable approach, no?


Doug
