為什么金額不對(duì)，感覺語法沒錯(cuò)呀
#include <stdio.h>
float Pay(float time ,float mail)
{float pay;
if(time>=5&&time<23){
if(mail<=3){
pay=14;
}else{
pay=14+(mail-3)*2.3;
}
}else{if(mail<=3){
pay=14;
}else{
pay=14+(mail-3)*2.3*1.2;
}
}
return pay;
printf("%f點(diǎn)打車%f公里付費(fèi)%f元",time,mail,pay);
}
int main()
{ int sum= Pay(9,12)+Pay(18,12);
printf("小明每天打車的總費(fèi)用為%d元",sum);
return 0;
}
