I'm doing a project in C ++ and I have a class called DataContext where I will have vectors that store objects of another class as member data. I want to perform a function that resieves a vector of any type of class to be able to add, search, delete or modify the objects belonging to said vector.

class DataContext
{
    private:
        vector<TarjetaCredito> listaTarjetas = vector<TarjetaCredito>();
        vector<Contrato> lvector<Contrato> listaContrato = vector<Contrato>();
    public:
        DataContext();
        virtual ~DataContext();
        static bool Create(vector<vector_de _cualquier_clase>);//METODO QUE QUIERO IMPLIMENTAR.
};

I thought that when passing the vector as an argument, where does the data type of the vector have to put a template, if that is correct, where would it be?

I hope you can help me, thank you very much.

Since the template is at the level of the member function, that is, it does not affect the class, it is normal to leave that function as a template only:

class DataContext
{
  private:
    vector<TarjetaCredito> listaTarjetas = vector<TarjetaCredito>();
    vector<Contrato> lvector<Contrato> listaContrato = vector<Contrato>();
  public:
    DataContext();
    virtual ~DataContext();

    template<class T>
    static bool Create(vector<T> &);
};

Since you mention that one of the objectives of the function is to modify the vector, it becomes a necessity that the function receives a reference to said vector.
