Question

北大ACM试题1005

我用C语言写的代码如下：请问为甚么总是presentation error?谢了。。。
#include <stdio.h>
#include <math.h>
#define SIZE 1000

struct coordinate
{
double x;
double y;
}point[SIZE];

int main()
{
int i;
int n;
struct coordinate point[SIZE];
double s ;
int year;
double p = 3.1415926;

scanf("%d", &n);
for ( i = 0; i <= n - 1; i++ )
{
scanf("%lf %lf", &point[i].x, &point[i].y);
}

for ( i = 0; i <= n - 1; i++ )
{
s = p * ( point[i].x * point[i].x + point[i].y * point[i].y );

year = s / 100;

printf("Property %d:This property will begin eroding in year %d.\n", i + 1, year + 1 );

}
printf("END OF OUTPUT.");

return 0;
}

Answer 1

很明显好不好
“：”后面跟着空一格的

Answer 2

input int data:
1
input 2 float data:
0.2 0.3
Property 1:This property will begin eroding in year 1.

Answer 3

presentation error

说明算法正确，计算结果也对，但是输出格式不符合要求，请写出题目地址。

Answer 4

少回车和空格。
