请指教 为什么 输出价格为0
# include<stdio.h>
int taixfee(int clock,int miles)
{
float total,cost;
if(clock>=5 && clock<23)
{
if(miles<=3)
cost=0;
else
cost=(miles-3)*2.3;
}
else
{
if(miles<=3)
cost=0;
else
cost=(miles-3)*2.3*1.2;
}
total =cost +14;
return total;
}
main()
{
printf("费用为%.1f",taixfee(9,12)+taixfee(18,12));
}
