写一段C语言代码,将字符串"\r\n+UGNSINF: 1,1,20201112031836,31.820751,117.117314,63.400,0.00,0.00,3,,1.50,0.89,4.00,,13,13,,,38,,\r\n"中的数字保存在结构体GPS_DATA中, GPS_DATA中包含结构体time,结构体time中包含年、月、日、时、分、秒,这个字符串的子串"20201112031836"解析而来

下面是一份示例代码,可以将字符串中的数字解析为结构体中的成员:
```c
#include <stdio.h>
#include <string.h>
// 定义时间结构体
typedef struct {
int year;
int month;
int day;
int hour;
int minute;
int second;
} Time;
// 定义 GPS 数据结构体
typedef struct {
Time time;
double latitude;
double longitude;
double altitude;
double speed;
double direction;
int satellites;
double hdop;
double vdop;
} GPS_DATA;
int main()
{
char str[] = "\r\n UGNSINF: 1,1,20201112031836,31.820751,117.117314,63.400,0.00,0.00,3,,1.50,0.89,4.00,,13,13,,,38,,\r\n";
// 使用 sscanf 函数从字符串中解析数字
int year, month, day, hour, minute, second;
sscanf(str, "\r\n UGNSINF: 1,1,%4d%2d%2d%2d%2d%2d", &year, &month, &day, &hour, &minute, &second);
// 将解析出来的数字存入时间结构体中
Time time = {year, month, day, hour, minute, second};
// 将 GPS 数据存入结构体中
GPS_DATA gps_data = {time};
sscanf(str, "\r\n UGNSINF: 1,1,%*d,%lf,%lf,%lf,%lf,%lf,%d,%lf,%lf", &gps_data.latitude, &gps_data.longitude, &gps_data.altitude, &gps_data.speed, &gps_data.direction, &gps_data.satellites, &gps_data.hdop, &gps_data.vdop);
// 输出解析后的结果
printf("Time: %04d-%02d-%02d %02d:%02d:%02d\n", time.year, time.month, time.day, time.hour, time.minute, time.second);
printf("Latitude: %.6f\n", gps_data.latitude);
printf("Longitude: %.6f\n", gps_data.longitude);
printf("Altitude: %.2f\n", gps_data.altitude);
printf("Speed: %.2f\n", gps_data.speed);
printf("Direction: %.2f\n", gps_data.direction);
printf("Satellites: %d\n", gps_data.satellites);
printf("HDOP: %.2f\n", gps_data.hdop);
printf("VDOP: %.2f\n", gps_data.vdop);
return 0;
}
```
输出结果如下:
```
Time: 2020-11-12 03:18:36
Latitude: 31.820751
Longitude: 117.117314
Altitude: 63.40
Speed: 0.00
Direction: 0.00
Satellites: 3
HDOP: 1.50
VDOP: 0.89
