c语言 我这个代码怎么补全，求解惑

在名称字段中存储第一个输入字符串
在类型字段中存储第二个输入字符串
将第三个输入字符串转换为int并将其存储在age字段中
将第四个输入字符串转换为整数并将其存储在weight字段中

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

#define MAX_NAME_LENGTH 50
#define MAX_TYPE_LENGTH 50

struct pet {
char name[MAX_NAME_LENGTH];
char type[MAX_TYPE_LENGTH];
int age;
int weight;
};

// function declarations, do not change these
void setup_pet(
struct pet *my_pet,
char *name,
char *type,
char *age,
char *weight
);
void print_pet(struct pet *my_pet);

// do not change any code in the main function
int main(int argc, char *argv[]) {
if (argc < 5) {
printf("%s should receive four extra command line arguments.\n", argv[0]);
return 1;
}
struct pet new_pet;
setup_pet(&new_pet, argv[1], argv[2], argv[3], argv[4]);
print_pet(&new_pet);
return 0;
}

// A function that takes in four strings
// (given from the command line arguments in the main function)
// and stores their data in the pet struct.
//
// Note: you will need to convert the 'age' and 'weight' strings
// to an integer before storing them in the struct.
void setup_pet(
struct pet *my_pet,
char *name,
char *type,
char *age,
char *weight
) {
// YOUR CODE GOES HERE
}

// A function that prints out a human readable
// description of the pet:
// " is a who is years old and weighs kg\n"
void print_pet(struct pet *my_pet) {
// YOUR CODE GOES HERE
}

代码如下：

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

#define MAX_NAME_LENGTH 50
#define MAX_TYPE_LENGTH 50

struct pet {
    char name[MAX_NAME_LENGTH];
    char type[MAX_TYPE_LENGTH];
    int age;
    int weight;
};

// function declarations, do not change these
void setup_pet(
struct pet *my_pet,
    char *name,
    char *type,
    char *age,
    char *weight
    );
void print_pet(struct pet *my_pet);

// do not change any code in the main function
int main(int argc, char *argv[]) {
    if (argc < 5) {
        printf("%s should receive four extra command line arguments.\n", argv[0]);
        return 1;
    }
    struct pet new_pet;
    setup_pet(&new_pet, argv[1], argv[2], argv[3], argv[4]);
    print_pet(&new_pet);
    return 0;
}

// A function that takes in four strings
// (given from the command line arguments in the main function)
// and stores their data in the pet struct.
//
// Note: you will need to convert the 'age' and 'weight' strings
// to an integer before storing them in the struct.
void setup_pet(
struct pet *my_pet,
    char *name,
    char *type,
    char *age,
    char *weight
    ) {
        // YOUR CODE GOES HERE
        strcpy(my_pet->name,name);
        strcpy(my_pet->type,type);
        my_pet->age = atoi(age);
        my_pet->weight = atoi(weight);
}

// A function that prints out a human readable
// description of the pet:
// " is a who is years old and weighs kg\n"
void print_pet(struct pet *my_pet) {
    // YOUR CODE GOES HERE
    printf("%s is a %s who is %d years old and weights %dkg\n",my_pet->name,my_pet->type,my_pet->age,my_pet->weight);
}
