c++ - Deleting resources managed by a vector -

i want vector hold pointers objects own.

here vector:

private: std::vector<fppvirtual*> m_fapps;

i have created elements this:

    m_fapps.push_back(new fpp1(renderingengine)); //fpp* subclasses of fppvirtual     m_fapps.push_back(new fpp2(renderingengine));     m_fapps.push_back(new fpp3(renderingengine)); 

as m_fapps vector instance variable in class, want make sure class's destructor cleans m_fapps:

       (int i=0, size=m_fapps.size();i<size;++i){         delete m_fapps[i];        } 

is acceptable memory management technique? assume loop needed since when vector goes out of scope when owning class destructed, pointers these new objects removed, right?

as no 1 gave straight forward answer yet - yes, acceptable , way free memory, having declaration of vector.

this can , should avoided, using smart pointers, @olicharlesworth suggested or using other container, ponited @björnpollex.
