在C中使用malloc进行序列化

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct {
    int id;
    char name[20];
    float score;
} Student;

int main() {
    // 创建一个学生对象
    Student student;
    student.id = 1;
    strcpy(student.name, "John");
    student.score = 95.5;

    // 序列化
    size_t size = sizeof(Student);
    void* buffer = malloc(size);
    memcpy(buffer, &student, size);

    // 反序列化
    Student* deserializedStudent = (Student*)buffer;
    printf("ID: %d\n", deserializedStudent->id);
    printf("Name: %s\n", deserializedStudent->name);
    printf("Score: %.1f\n", deserializedStudent->score);

    // 释放内存
    free(buffer);

    return 0;
}
