VC读取txt文件数据问题

[wjl20060620]

txt文件
1 1.001 0
2 2.001 0
3 2.998 0
4 3.999 0
#include <stdio.h>
#include <stdlib.h>
void main()
{
FILE *fp1;
double x1=0,y1=0,x1_x1=0,x1_y1=0;
int n;
int i;
printf("input n\n");
scanf("%d",&n);
struct point_type
{
double x;
double y;
double z;
};
struct point_type point[3000];
if((fp1=fopen("zhixian.txt","r"))==NULL)
{
printf("cant not open file");
exit(1);
}

for(i=0;i<n;i++)
{
fscanf(fp1,"%lf %lf",point[i],&point[i].x,&point[i].y);
x1+=point[i].x;
y1+=point[i].y;
x1_y1+=point[i].x*point[i].y;
x1_x1+=point[i].x*point[i].x;
}
fclose(fp1);
}
为什么不能运行？

lz的fscanf(fp1,"%lf %lf",point[i],&point[i].x,&point[i].y);语句参数不匹配

#include "stdafx.h"

#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;

void main()
{
	FILE *fp1;
	double x1=0,y1=0,x1_x1=0,x1_y1=0;
	int n;
	int i;
	printf("input n\n");
	scanf("%d",&n);
	struct point_type
	{
		double x;
		double y;
		double z;
	};
	struct point_type* point = new point_type[n];
	memset(point, 0, n*sizeof(point_type));

	if((fp1=fopen("F:\\11.txt","r"))==NULL)
	{
		printf("cant not open file");
		exit(1);
	}
	
	for(i=0;i<n;i++)
	{
		fscanf(fp1,"%lf %lf %lf",&point[i].x,&point[i].y, &point[i].z);
		x1+=point[i].x;
		y1+=point[i].y;
		x1_y1+=point[i].x*point[i].y;
		x1_x1+=point[i].x*point[i].x;
	}
	printf("x1 = %.3lf\n", x1);
	printf("y1 = %.3lf\n", y1);
	printf("x1_y1 = %.3lf\n", x1_y1);
	printf("x1_x1 = %.3lf\n", x1_x1);

	delete[] point;
	fclose(fp1);
}

恩，和楼上一样，学习学习！

fscanf(fp1,"%lf %lf",point[i],&point[i].x,&point[i].y);
去掉第一个point[i]
