Vector Iterators Incompatible

Question

I have a class with a std::vector data member e.g.

class foo{
public:

const std::vector getVec(){return myVec;} //other stuff omitted

private:
s         


        

Answer 1

The problem is that you always return another copy of the vector. Use a reference:

const std::vector& getVec(){return myVec;} //other stuff omitted
