实验3-9 三天打鱼两天晒网 (15分)

国有句俗语叫“三天打鱼两天晒网”。假设某人从某天起，开始“三天打鱼两天晒网”，问这个人在以后的第N天中是“打鱼”还是“晒网”？

输入格式：

输入在一行中给出一个不超过1000的正整数N。

输出格式：

在一行中输出此人在第N天中是“Fishing”（即“打鱼”）还是“Drying”（即“晒网”），并且输出“in day N”。

输入样例1：

103

 

输出样例1：

Fishing in day 103

 

输入样例2：

34

 

输出样例2：

Drying in day 34

#include<stdio.h>

int main()

{

    int n;

    int t;

    scanf("%d",&n);

    if(n>0&&n<=10000)

    {

        //5是指三+二

        t=n%5;

    //  printf("%d ",t);

        if(t==1||t==2||t==3)

         {

            printf("Fishing in day %d",n);

         }

         else if(t==0||t==4||t==5)

        {

            printf("Drying in day %d",n);

         }

     }

    return 0;
