求大神幫忙看看小弟的代碼哪里不對?。吭趺摧敵隹偸秋@示0元？
#include<stdio.h>
double?getcharge(int?mile,int?time)
{
double?unit;
if(time<23?&&?time>=5)
{
if(mile>3)
{
unit=14+(mile-3)*2.3;
}
else?if(mile>3)
{
unit=14+(mile-3)*2.76;
}
else?if?(mile<3)
{
unit=14;
}
}
return?0;
}
int?main()
{
double?x;
double?y;
double?price;
x=getcharge(12,9);
y=getcharge(12,6);
price=x+y;
printf("小明每天打車費用為%.1f元\n",price);
return?0;
}

return 0;的話返回值就是0，所以····你也知道了····

貌似找到問題了，自定義函數返回值應該設為return unit; ?= =。
