    Now what's wrong with this STL code

    Same code as last thread but different error message. I went from VC2008 to VC2012 and I'm getting this error. Not sure why. Previous error was fixed by #include <iterator> on a different computer. Current computer is generating this error.

    error C2784: void STLCopy(tSTLContainer *,const tSTLContainer *)' : could not deduce template argument for 'tSTLContainer *' from 'std::vector<_Ty,_Alloc>'

    Code:
    template 
    <
    	class tSTLContainer			// The type of STL container to copy.
    >
    void STLCopy (tSTLContainer* outDest, const tSTLContainer* inSource)
    {
    	copy(inSource->begin(), inSource->end(), insert_iterator<tSTLContainer>(outDest, outDest->begin()));
    }
    Once again, never mind. Changing pointers to references fixed it, but I'm not sure why.

    1. That would have been my suggestion.

    2. Keeping as pointers:

    Code:
    copy(inSource->begin(), inSource->end(), insert_iterator<tSTLContainer>(*outDest, outDest->begin()));
    
    std::vector<int> v1;
    std::vector<int> v2;
    STLCopy(&v2,&v1);

    And that prooves the point I made in that other thread. pointers confuse programmers (even seasoned ones) :-)
