Question

北大ACM试题1005 急!!!!!!

下面是我的代码,错在何处? 我在visualc++6.0上成功了,可是......
#include<stdio.h>
int main()
{
int times,n,i;
double x,y;
scanf("%d",×);
for(i=0;i<=times-1;i++)
{
scanf("%lf %lf",&x,&y);
n=1;
while((100*n/3.1415926)<(x*x+y*y))
n=n+1;
printf("Property %d: This property will begin enroding in year %d.\n",i+1,n);
}
printf("END OF OUTPUT.\n");
return 0;
}
程序第6行是
scanf("%d",与times);
复制时有错误 与号打不上

Answer 1

就你这程序，怎么可能对呢？！！

Answer 2

#include<stdio.h>
int main()
{
int times,n,i;
double x,y;
scanf("%d",x);
for(i=0;i<=times-1;i++)
{
scanf("%lf %lf",&x,&y);
n=1;
while((100*n/3.1415926)<(x*x+y*y))
n=n+1;
printf("Property %d: This property will begin enroding in year %d.\n",i+1,n);
}
printf("END OF OUTPUT.\n");
return 0;
}

Answer 3

scanf("%d",×); --- scanf("%f",&x); x是小写,C语言是有大小写之分的.
for(i=0;i<=times-1;i++) times 没初始值.

Answer 4

scanf("%d",×); ???
