Parse GPS String for Time and Coordinates

Code

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

void parse_gprmc(char *nmea) {
    // Your logic here
    char *time, *latitude, *longitude, *dir1, *dir2;
    strtok(nmea, ",");
    time = strtok(NULL, ",");
    strtok(NULL, ",");
    latitude = strtok(NULL, ",");
    dir1 = strtok(NULL, ",");
    longitude = strtok(NULL, ",");
    dir2 = strtok(NULL, ",");

    printf("Time: %c%c:%c%c:%c%c\n",*time,*(time+1),*(time+2),*(time+3),*(time+4),*(time+5));
    printf("Latitude: %s %c\n", latitude, *dir1);
    printf("Longitude: %s %c\n", longitude, *dir2);
}

int main() {
    char nmea[100];
    fgets(nmea, sizeof(nmea), stdin);
    parse_gprmc(nmea);
    return 0;
}
