顺序表的查找

代码：

#include<stdio.h>
#define listsize 50
struct sequenlist
{
	int data[listsize];
	int length;
};
struct sequenlist L;
int find(struct sequenlist L,int x)
{
	int i=0;
	while(i<L.length&&L.data[i]!=x) i++;
	if(i<L.length) return(i);
	else		return(0);
}
int main(void)
{
	int i,j,y;
	struct sequenlist a;
	scanf("%d",&a.length);
	scanf("%d",&j);
	for(i=0;i<a.length;i++)
		scanf("%d",&a.data[i]);
	y=find(a,j);
	if(y) printf("%d\n",y);
	else  printf("no find");
	return(0);
}

运行结果：
