class MForwardInfo { public: MForwardInfo(MProjectInfo* info) :projectInfo(info) { ; } MForwardInfo() { }; ~MForwardInfo(); QString name; QString describe; QStringList dataInfo[5]; MProjectInfo* projectInfo; }给这个类经行深拷贝构造，并且重载=运算发，注意：projectInfo 中包含了MForwardInfo 类的链表，请给出你的答案

以下是深拷贝构造和重载=运算符的代码实现：

class MForwardInfo {
public:
    // 深拷贝构造函数
    MForwardInfo(const MForwardInfo& other) {
        name = other.name;
        describe = other.describe;
        for (int i = 0; i < 5; i++) {
            dataInfo[i] = other.dataInfo[i];
        }
        if (other.projectInfo) {
            projectInfo = new MProjectInfo(*other.projectInfo);
        }
    }
    
    // 重载=运算符
    MForwardInfo& operator=(const MForwardInfo& other) {
        if (this != &other) {
            name = other.name;
            describe = other.describe;
            for (int i = 0; i < 5; i++) {
                dataInfo[i] = other.dataInfo[i];
            }
            if (other.projectInfo) {
                projectInfo = new MProjectInfo(*other.projectInfo);
            }
            else {
                projectInfo = nullptr;
            }
        }
        return *this;
    }
    
    ~MForwardInfo() {
        if (projectInfo) {
            delete projectInfo;
        }
    }
    
    QString name;
    QString describe;
    QStringList dataInfo[5];
    MProjectInfo* projectInfo = nullptr;
};

需要注意的是，在进行深拷贝时，需要特别处理 projectInfo 指针所指向的 MProjectInfo 对象，因为它也包含了 MForwardInfo 类的链表，需要进行递归深拷贝。同时，在析构函数中，需要释放 projectInfo 指针所指向的内存，避免内存泄漏。
