inheretence and filling Vector with custom class

C++

Hi All,

In my application i've 2 classes, a Base one (callaed Categorie) and a derived one (called CAT1). I create a vector of my custom class CAT1 and i tried to fill that vector with CAT1 elements using the push_back function:

Below are the declaration of my classes :

[Base Class]

class Categorie
{
    //Attributs
public:
    int ID;
    string Fournisseur;
    int Min;
    int Quantite;
    float Prix_Vente;
    //Constructeurs
public:
    Categorie(int ID, string Fournisseur, int Min, int Quantite, float Prix_Vente)
    {
        this->ID = ID;
        this->Fournisseur = Fournisseur;
        this->Min = Min;
        this->Quantite = Quantite;
        this->Prix_Vente= Prix_Vente;
    }

    Categorie(const Categorie & CSrc)
    {
        this->ID = CSrc.ID;
        this->Fournisseur = CSrc.Fournisseur;
        this->Min = CSrc.Min;
        this->Quantite = CSrc.Quantite;
        this->Prix_Vente= CSrc.Prix_Vente;
    }
};

[End Base Class]

[Derived Class]

class CAT1: public Categorie
{
    //Attributs
public:
    string Utilite;
    //Constructeurs
    CAT1(int ID, string Fournisseur, int Min, int Quantite, float Prix_Vente, string Utilite):
        Categorie(ID,Fournisseur, Min, Quantite, Prix_Vente), Utilite(Utilite){}

    CAT1(const CAT1 & CSrc) : Categorie(CSrc), Utilite(CSrc.Utilite){}

};

[End Derived Class]

And here the lines that i wrote to fill the vector with elements if CAT1:

CAT1 * instance;
instance = AjoutCAT1(); // declared CAT1* AjoutCAT1(){...}
CAT1Vct.push_back(instance);

When Compiling i got this error :

error C2664: 'push_back' : cannot convert parameter 1 from 'class CAT1 *' to 'const class CAT1 &'<br />

what's wrong and how fix it ?

Thank you.
