Struct Time

Kode :

typedef struct Time {

  int minutes;
  int seconds;
} Time;

Contoh Implementasi :

Time sekarang;
sekarang.hours = 13;
sekarang.minutes = 15;
sekarang.seconds = 50;

printf("Sekarang jam %d:%d:%d\n", sekarang.hours, sekarang.minutes, sekarang.seconds);

Fungsi clear

Kode :

void clear(void) {
  #ifdef _WIN32
    system("cls");
  #else
    system("clear");
  #endif /* _WIN32 */
}

Contoh Implementasi :
```
clear();
```

Fungsi gettimenow

Kode :

  Time result = {
    .hours = ttmm->tm_hour,
    .minutes = ttmm->tm_min,
    .seconds = ttmm->tm_sec,
  };
  return result;
}

Contoh Implementasi :

      i++;
    } else if(i !=0 && (tmp == '\b' || tmp == (char)127)) {
      int len = strlen(prompt) + i;
      for(int j = 0; j < len; j++) printf("\r");
      for(int j = 0; j < len; j++) printf(" ");
      for(int j = 0; j < len; j++) printf("\r");
      printf("%s", prompt);
      for(int j = 0; j<i-1; j++) printf("*");
      pass[i] = '\0';
      i--;
    }

  }
  dest[index] = '\0';
  printf("\n");

      if(input == tolower(keys[i])) (*score)++;
    }
  }
