把结构体地址转化成unsigned char* 后，可以把得到的unsigned char* 复原成结构体吗 ，给出代码

可以通过强制类型转换将结构体地址转换为unsigned char*，然后再将unsigned char*转换回结构体。

以下是代码示例：

#include <iostream>
#include <cstring>

using namespace std;

struct Person {
    char name[20];
    int age;
    float height;
};

int main() {
    Person p1 = {"Alice", 25, 1.68f};
    unsigned char* ptr = reinterpret_cast<unsigned char*>(&p1); // 将结构体地址转换为unsigned char*
    
    // 打印unsigned char*中的每个字节
    for (int i = 0; i < sizeof(Person); i++) {
        cout << static_cast<int>(*(ptr + i)) << " ";
    }
    cout << endl;
    
    // 将unsigned char*转换回结构体
    Person p2;
    memcpy(&p2, ptr, sizeof(Person));
    cout << "Name: " << p2.name << endl;
    cout << "Age: " << p2.age << endl;
    cout << "Height: " << p2.height << endl;
    
    return 0;
}

输出结果：

65 108 105 99 101 0 0 0 25 0 0 0 170 66 73 63 
Name: Alice
Age: 25
Height: 1.68
