为什么我给队列指针分配内存的时候它总是编译不通过

MY_Quen::MY_Quen(int quentCapacity)

{

    m_QuenCapacity=quentCapacity;

    m_head=0;

    m_tail=0;

    m_Quen=new Customer[m_QuenCapacity];

    m_Quenlength=0;

    }

class Customer

{

    public:

        Customer(string name,int age);

        virtual ~Customer();

        void printInof();

    private:

        string   name_customer;

        int age_customer;

};

Customer::Customer(string name,int age)

{

    name_customer=name;

    age_customer=age;

}
