That's not the case in C, C++, Java, or Ada. In C and C++, for example, given two arrays
int X[50]; int Y[100];
and a function declared as
void P( int a[] )
then these calls
P( X ) P( Y )
are both valid, because the sizes of X and Y are not part of their type.
But here you don't pass the array but a pointer to its first element. You can even call P(&x) where x is an int, not an array at all. Consider this: int X[50]; int Y[100]; void P(int (&a)[50]) {} int main() { P(X); // valid P(Y); // invalid }
In C and C++, there's not even any way for a function to discover the size of an array argument.
template<int N> int size(int (&a)[N]) { return N; } -- __("< Marcin Kowalczyk \__/ qrczak@knm.org.pl ^^ http://qrnik.knm.org.pl/~qrczak/
