c++中的动态内存释放问题
 #include<iostream>

using namespace std;

class CGoods

    long no;
    char *p_name;
    double price;

    CGoods(long no1, char *p_name1, double price1);
    CGoods(const CGoods &C)         //深度拷贝构造函数
    {
        no = C.no;
        int n = strlen(C.p_name);
        p_name = new char[n + 1];
        strcpy(p_name, C.p_name);
        price = C.price;
    }
    void show();

    virtual ~CGoods()
    {
        cout << "nkhao啊" << p_name << endl;

        int n = strlen(p_name1);
        p_brand = new char[n + 1];
        strcpy(p_brand, p_brand1);
    }
    void usedFor()
    {
        Cc.show();
        cout << p_brand << endl;
    }
    ~CFood()
    {
        delete[]p_brand;
    }

};
int main()
{
    long no;
    char *p= new char[1];
    double price;
    char *p1 = new char[1];
    cin >> no >> p >> price >> p1;
    CClothes ccl(no, p, price, p1);
    ccl.usedFor();
    cin >> no >> p >> price >> p1;
    CFood cfood(no, p, price, p1);
    cfood.usedFor();
    /*delete[]p;
    delete[]p1;*/
    return 0;
}

为什么在释放内存的时候,最后一次发生了冲突??
(我在析构函数中加cout << "nkhao啊" << p_name << endl;是方便结果分析)

name 父类的,有没赋值的情况
