怎样拷贝两个结构？看看小弟我错在哪里

怎样拷贝两个结构？看看我错在哪里？
struct TextData
{
int x;
int y;
};

struct PhotoData
{
TextData TextData;
};

PhotoData *a=new PhotoData;
PhotoData *b=new PhotoData;

memcpy(a, b, sizeof(PhotoData));//b拷贝到a

delete a;
delete b;

[解决办法]
既然是c++对象之间的赋值就不要用memcpy ，直接 *a=*b;即可
[解决办法]
这样没错吧

C/C++ code

#include<iostream>using namespace std;struct TextData{int x;int y;};struct PhotoData{TextData TextData;};int main(){    PhotoData *a=new PhotoData;    PhotoData *b=new PhotoData;        memcpy(a, b, sizeof(PhotoData));//b拷贝到a        delete a;    delete b;return 0;}
