在C中复制包含char指针的两个结构

typedef struct {
    char* name;
    int age;
} Person;

Person person1;
person1.name = malloc(sizeof(char) * (strlen("John") + 1));
strcpy(person1.name, "John");
person1.age = 25;

Person person2;
person2.name = malloc(sizeof(char) * (strlen("Jane") + 1));
strcpy(person2.name, "Jane");
person2.age = 30;

Person person3;
person3.name = malloc(sizeof(char) * (strlen(person1.name) + 1));

strcpy(person3.name, person1.name);

free(person1.name);
free(person2.name);
free(person3.name);
