如何将此字符串指向结构？

typedef struct {
    char name[50];
    int age;
    char address[100];
} Person;

char personStr[] = "John Doe,25,123 Main St";

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

int main() {
    char personStr[] = "John Doe,25,123 Main St";
    Person person;

    char *token = strtok(personStr, ",");
    strcpy(person.name, token);

    token = strtok(NULL, ",");
    person.age = atoi(token);

    token = strtok(NULL, ",");
    strcpy(person.address, token);

    printf("Name: %s\n", person.name);
    printf("Age: %d\n", person.age);
    printf("Address: %s\n", person.address);

    return 0;
}
