Question

I got this error and I can’t figure out why.

#include <vector>
#include <cstdlib>

#ifndef PERSONALVEC_HPP_
#define PERSONALVEC_HPP_

template <class T,class PrnT>

class PersonalVec
{
public:
    PersonalVec() {}

    ~PersonalVec()
    {
        //TODO: delete vector.
    }

    void push_back(T& obj)
    {
        int index = rand()%_vec.size();
    }

private:
    vector<T*> _vec;
};

#endif /* PERSONALVEC_HPP_ */

Answer 1

Both rand and vector are in the std namespace.
Use

private:
std::vector<T*> _vec;

and

std::rand()
