    Re: Is this legal C++?

    I believe that what you are doing is portable. I think the scope of the tempory object is defined by the output stream's "<<" operator. If you are uncertain, why not introduce a temporary?

    Re: How much extra memory std::vector uses?

    There is very little overhead. For example, comparing the memory usage between:



    #include <unistd.h> // sleep is declared here

    class AClass

    AClass(int n){

    Re: [C++] methods template specialization

    I think method specializations have to be based off of the classes templated parameters (but I could be wrong). In any case, a workaround for what you want to do would be to introduce a templated...

    First step is to know what you need.
