在c ++中复制构造函数

class ClassName {
public:
    ClassName(const ClassName& other);
};

class MyClass {
private:
    int* m_pData;

public:
    MyClass(int* data) {
        m_pData = new int;
        *m_pData = *data;
    }

    MyClass(const MyClass& other) {
        m_pData = new int;
        *m_pData = *other.m_pData;
    }
};
