22014的吃瓜群众有问题，比如6分为两半各为3，不是偶数，不可以分，应输出NO，正确代码应为

#include<stdio.h>
int main()
{
    int a,b,c;
    scanf("%d",&a);
    if(a%2==0){
        b=a/2;
        c=b%2;
        if(c==0&&a>2)
        printf("YES, you can divide the watermelon into two even parts.");
        else
            printf("NO, you can't divide the watermelon into two even parts.");
    }
    else
        printf("NO, you can't divide the watermelon into two even parts.");
    return 0;
}
