哪儿错了？

#include <stdio.h>
double getPrice (int hours,double distances)
{
    double getPrice=0;
    double distances=0;
    int startPrice=13;
    double perPrice=2.3;
    if(hours<0 || hours>24)
    {
        printf("请输入正确时间\n");
    }
    if(hours<5 && hours>=23)
    {
        perPrice*=1.2;
    }
    if(distances>3)
    {
        getPrice=startPrice+perPrice*(distances-3);
    }
    else if
    {
        getPrice=startPrice;
    }
    getPrice+=1;
    return totalPrice;
}
int main()
{
    int totalPrice;
    double getPriceMoring=getPrice(9,12);
    double getPriceEvening=getPrice(18,12);
    double totalPrice=getPriceMoring+getPriceEvening;
    printf("小明每天打车的总费用为%f\n",totalPrice);
   return 0;
}
