Question

c++结构体重载运算符出现0xC0000005: 写入位置 0xcdcdcdcd 时发生访问冲突错误,怎么解决求大神！

这汇编看不懂~~~

右边的数据传进去了，但是左边提示<错误的指针>
部分代码如下：
typedef struct stu//学生结构体（含学生信息和学生成绩）
{
typedef struct StuInfo//学生信息
{
string stuNo;
string stuBrithday;
string stuIdno;
string stuName;
string stuSex;
StuInfo &operator = (StuInfo &student)
{
stuBrithday = student.stuBrithday;
stuIdno = student.stuIdno;
stuName = student.stuName;
stuSex = student.stuSex;
stuNo = student.stuNo;
return *this;
}
}stuInfo;
stuInfo stu_info;
typedef struct StuScore//学生成绩
{
int stuMath;
int stuEnglish;
int stuDatastruct;
StuScore &operator = (StuScore &student)
{
stuDatastruct = student.stuDatastruct;
stuEnglish = student.stuEnglish;
stuMath = student.stuMath;
return *this;
}
}stuScore;
stuScore stu_score;
stu &operator = (stu &student)
{
stu_info = student.stu_info;
stu_score = student.stu_score;
return *this;
}
}Stu;

Answer 1

struct类,不能有成员函数,改成class,然后重载的=号要声明为友元

追问

谢谢你的解答，可是并不是我所想要的~~struct结构体也能重载，友元只是能让它在外部定义~~
