如何通过指向指针的指针访问结构成员

typedef struct {
    int age;
    float height;
} Person;

Person *personPtr1; // 指向Person结构的指针
Person **personPtr2; // 指向Person指针的指针

personPtr1 = (Person *) malloc(sizeof(Person));

(*personPtr2)->age = 25;
(*personPtr2)->height = 175.5;

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

typedef struct {
    int age;
    float height;
} Person;

int main() {
    Person *personPtr1; // 指向Person结构的指针
    Person **personPtr2; // 指向Person指针的指针

    personPtr1 = (Person *) malloc(sizeof(Person));
    personPtr2 = &personPtr1; // 将personPtr1的地址赋给personPtr2

    (*personPtr2)->age = 25;
    (*personPtr2)->height = 175.5;

    printf("Age: %d, Height: %.1f
", personPtr1->age, personPtr1->height);

    free(personPtr1);
    return 0;
}
