我是靠谱客的博主柔弱秀发，最近开发中收集的这篇文章主要介绍CodeForces - 4A. Watermelon（C语言），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

One hot summer day Pete and his friend Billy decided to buy a watermelon. They chose the biggest and the ripest one, in their opinion. After that the watermelon was weighed, and the scales showed w kilos. They rushed home, dying of thirst, and decided to divide the berry, however they faced a hard problem.

Pete and Billy are great fans of even numbers, that's why they want to divide the watermelon in such a way that each of the two parts weighs even number of kilos, at the same time it is not obligatory that the parts are equal. The boys are extremely tired and want to start their meal as soon as possible, that's why you should help them and find out, if they can divide the watermelon in the way they want. For sure, each of them should get a part of positive weight.

Input

The first (and the only) input line contains integer number w (1 ≤ w ≤ 100) — the weight of the watermelon bought by the boys.

Output

Print YES, if the boys can divide the watermelon into two parts, each of them weighing even number of kilos; and NO in the opposite case.

   Examples 
 
     input 
   
8

     output 
   
YES

Note

For example, the boys can divide the watermelon into two parts of 2 and 6 kilos respectively (another variant — two parts of 4 and 4 kilos).

C语言AC代码

#include<stdio.h>
int main()
{
    int w;
    while(scanf("%d",&w)!=EOF)
    {
        if(w%2==0&&w!=2)
            printf("YESn");
        else
            printf("NOn");
    }
    return 0;
}

这道题还真把我逗乐了，因为一看题目even number就可以，所以刚开始就直接判断是不是偶数去了，结果WA了两次，原来没有考虑当W=2的时候是不能分成两个偶数的，我这个脑子啊。。。
