with get functions, use pointer or declare function as?

Hi, with my 'get' functions eg: quote: int getNumber() { return number; } ...should I put the function like the one above, or should I do it like this: quote: void getNumber(int * returnNumber) { returnNumber= number; } Like my get functions would include things like LONGLONG, string, int, float, double, long. Most of the microsft dx functions use the pointer way,... whats the difference. Like memory wise or something. I actually prefer using ones where they return a value so i don't have to create a variable for the value to be entered in. Thanks, [edited by - johnnyBravo on April 21, 2004 4:43:24 AM]

a simple rule I follow for accessors is for pods return by value for udts return by const reference

if you think programming is like sex, you probably haven't done much of either.-------------- - capn_midnight

if return is not class thingo I no use & on type. If I define a clas thing I use squigily and sign thing

If you''re returning an objects, return by const reference. For plain old data types, return by value.

std::string const& GetName();int GetID();

Could you define the terms "squigily" and "thingo"? Thank you.
