Title Description
2013 onwards, the proportion of ticket refund fee reduction: par car station more than 48 hours before the drive time by 5% per ticket refund fee. Meanwhile, the ticket refund fee calculation method is no longer rounded to units of cells but in units of angle 5: less than 0.25 membered rounding the mantissa is not less than 0.25 and less than 0.75 membered element is 0.5 yuan, is not less than 0.75 yuan into $ 1. Write a function to calculate refunds example assumed refund driving time period more than 48 hours. The following function prototype:
Double CancelFee (Double. Price);
this is a problem if the C / C ++ code delivery submitted only CancelFee function definition part, other content submission, compile error.

Enter
Enter a real number, the ticket face value.

Output
Output a real number, the fee refund, the results to one decimal place.

Enter
106

Output
5.5

One

#include<stdio.h>
double CancelFee(double price)
{
    double t,x;
    t=price*0.05;
    x=(int)t;//强制取整
    if(t-x>=0&&t-x<0.25) x+=0;
    else if(t-x>=0.25&&t-x<0.75) x+=0.5;
    else x+=1;
    //printf("%.1lf",x);
    return x;
}
int main()
{
    double n;
    scanf("%lf",&n);
    n=Cancelfee(n);
    printf("%.1lf")
    return 0;
}

two

#include <bits/stdc++.h>
 
using namespace std;
 
double CancelFee(double m)
{
    int x = m * 5;
    int d = x / 100,  s = x % 100;
    double t;
    if(s >= 75)
        t = 1;
    if(s >= 25 && s < 75)
        t = 0.5;
    return 1.0 * d + t ;
}
int main()
{
    double x ;
    scanf("%lf",&x);
    double m = CancelFee(x);
    printf("%.1f\n",m);
    return 0;
