5-14中關于在晚上23點(含)至次日凌晨5點(不含)打車，每公里單價計費加收20%的計算
這個為啥不行
#include?<stdio.h>
float?fee(t)
{???
????int?f=14;
????int?n=12;
????float?fee;
????if(n<=3)
????{
????????fee=f;
????}
????else
????{?
????????float?d;
????????fee=f+d*(n-3);
????????if(5<=t<=23)
????????{
????????????d=2.3;
????????}
????????else
????????{
????????????d=2.3*1.2;
????????}
????}
????return?fee;
}
int?main()
{
????printf("fee=%f",fee(9)+fee(18));
????return?0;
}這個就行
#include?<stdio.h>
float?fee(t)
{???
????int?f=14;
????int?n=12;
????float?fee;
????if(n<=3)
????{
????????fee=f;
????}
????else
????{?
????????if(5<=t<=23)
????????{
????????????fee=f+2.3*(n-3);
????????}
????????else
????????{
????????????fee=f+2.3*(n-3)*1.2;
????????}
????}
????return?fee;
}
int?main()
{
????printf("fee=%f",fee(9)+fee(18));
????return?0;
}呢？
