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; }
