解题思路：

其实本题只要能读懂题意就行，大意就是输入中的单词若是餐桌用具就输出即可

可以将每个单词用字符串读入，再用strcmp（a，b）==0语句比较，该语句成立，就输出即可。

程序代码：

#include<stdio.h>
#include<string.h>
int main()
{
	int n;
	char a[20];
	while(scanf("%d",&n)!=EOF)
	{
		for(int i=0;i<n;i++)
		{
			scanf("%s",a);
			if(strcmp(a,"bowl")==0||strcmp(a,"knife")==0||strcmp(a,"fork")==0||strcmp(a,"chopsticks")==0)
				printf("%s ",a);
		}
		printf("\n");
	}
}
