class MForwardInfo { public: MForwardInfo(MProjectInfo* info) :projectInfo(info) { ; } MForwardInfo() {}; ~MForwardInfo();QString name; QString describe; QStringList dataInfo[5]; MProjectInfo* projectInfo;} 给这个类进行深拷贝构造，并重载=号

深拷贝构造函数：

MForwardInfo::MForwardInfo(const MForwardInfo& other) {
    name = other.name;
    describe = other.describe;
    for (int i = 0; i < 5; i++) {
        dataInfo[i] = other.dataInfo[i];
    }
    projectInfo = new MProjectInfo(*other.projectInfo);
}

重载赋值运算符：

MForwardInfo& MForwardInfo::operator=(const MForwardInfo& other) {
    if (this == &other) {
        return *this;
    }
    name = other.name;
    describe = other.describe;
    for (int i = 0; i < 5; i++) {
        dataInfo[i] = other.dataInfo[i];
    }
    delete projectInfo;
    projectInfo = new MProjectInfo(*other.projectInfo);
    return *this;
}

需要注意的是，在进行深拷贝时，需要对类中指针类型的成员变量进行拷贝，而不是简单地复制指针地址。在实现中，我使用了MProjectInfo类的拷贝构造函数进行了拷贝。在重载赋值运算符时，需要先释放原有的资源，再进行深拷贝。同时，需要注意自我赋值的情况，避免出现内存泄漏。
