I have a quick question regarding const-correctness for getters of vector of non-pointers. Basically, I have this class with a non-const getter and a const getter for m_Vertices: class Mesh { public: std::vector<Vertex>& GetVertices() { return m_Vertices; } const std::vector<Vertex>& GetVertices() const { return m_Vertices; } private: std::vector<Vertex> m_Vertices; } The non-const getter makes sense… Read More Const-correctness with getters of vector of non-pointers

I want my class Foo to expose it’s base class Bar only as a const reference to Bar. This would mean that the members of Bar could be read, but not set. This is what I’ve tried: struct Bar { int member; }; class Foo : protected Bar { public: operator const Bar&() { return… Read More How to expose a base class only as const reference

Normally people write the main function like this: int main( int argc, char** argv ) However, this came to my mind: int main( const int argc, const char* const* const argv ) or maybe I should write it like this cause it seems more intuitive: int main( const int argc, const char *const *const argv… Read More What does each of these `const`s mean?
