The reason it's clear is that + means addition, and * means multiplication, exactly as you'd expect. > Of course, this is usually the time at which the C++ folks come out of > the background and start talking about objects, interfaces, overloading, ... > > Anyone ever debugged an overloaded operator? It ain't fun, at any level. Operator overloading reminds me of Bill Clinton's: "It depends what the meaning of 'is' is." If operator overloading is used unwisely, so that the meaning of "+" is not just "addition of this type of data", then pity the poor schmuck who has to maintain the code. Unfortunately you don't have to look far for data types where there is no single operator overload mapping that makes sense. If A,B,C,D are 3D vectors then + has a single obvious meaning, but * is ambiguous, is it a dot product or a cross product? That's the point where C++ overloading breaks down, at least for me, and a function or #define is easier to work with, something like : A = B + CROSS_PRODUCT(C,D) Regards, David Mathog [EMAIL PROTECTED] Manager, Sequence Analysis Facility, Biology Division, Caltech _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
