Parse GPS String for Time and Coordinates

Code

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

void parse_gprmc(char *nmea) {
    // Your logic here
    while(*nmea != ','){
        nmea++;
    }
    nmea++;
    printf("Time: ");
    int n = 0;
    while(*nmea != ','){
        if(n%2 == 0 && n != 0){
            printf(":");
        }
        printf("%d",*nmea-'0');
        n++;
        nmea++;
    }
    nmea+=3;
    printf("\nLatitude: ");
    while(*nmea != ','){
        if(*nmea == '.'){
            printf(".");
        }else{
            printf("%d",*nmea-'0');
        }
        nmea++;
    }
    nmea++;
    printf(" %c\n",*nmea);
    nmea+=2;
    printf("Longitude: ");
    while(*nmea != ','){
        if(*nmea == '.'){
            printf(".");
        }else{
            printf("%d",*nmea-'0');
        }
        nmea++;

}

int main() {
    char nmea[100];
    fgets(nmea, sizeof(nmea), stdin);
