如題，思路應(yīng)該是對(duì)的但是輸出就是68元

#include?<stdio.h>int?getDistance(int?distance,int?t){????float?money;????if(distance?<=?3)?//路程小于3不論白天夜晚都是13元????{????????money?=?13;????}else{????????if?(t?>=?5?&&?t?<23)//若白天????????{????????????money?=?13+(distance-3)*2.3+1;????????}else{????????????money?=?13+(distance-3)*2.3*1.2+1;//若夜間????????}????}????return?money;}int?main(){????float?sum;????sum?=?getDistance(12,9)+getDistance(12,16);????printf("小明每天打車花費(fèi)%f元",?sum);????return?0;}
