为什么输入数据之后会出现输出不了和答案错哪里出了问题

#include<stdio.h>
#include<math.h>
int main()
{
double x1,y1,r1,x2,y2,r2,d;
while(scanf("%lf%lf%lf%lf%lf%lf",&x1,&y1,&r1,&x2,&y2,&r2)!=EOF)
{
d=sqrt(fabs(x1-x2)*fabs(x1-x2)+fabs(y1-y2)*fabs(y1-y2));
if(d>r1+r2)
{
printf("disjoint\n");
}
else if(fabs(r1-r2)<d)
{
printf("contain\n");
}
else if(fabs(r1-r2)==d)
{
printf("internally tangent\n");
}
else if(r1+r2==d)
{
printf("externally tangent\n");
}
else if(d>fabs(r1-r2)&&d<fabs(r1+r2))
{
printf("overlap\n");
}

}
return 0;

}

原样例是分两行输入,你也要分两次读取,因为一个回车前面只包含三个数据
尝试改为

#include <stdio.h>
#include <math.h>
int main()
{
    double x1, y1, r1, x2, y2, r2, d;
    while (scanf("%lf%lf%lf", &x1, &y1, &r1), scanf("%lf%lf%lf", &x2, &y2, &r2) != EOF)
    {
        d = sqrt(fabs(x1 - x2) * fabs(x1 - x2) + fabs(y1 - y2) * fabs(y1 - y2));
        if (d > r1 + r2)
        {
            printf("disjoint\n");
        }
        else if (fabs(r1 - r2) < d)
        {
            printf("contain\n");
        }
        else if (fabs(r1 - r2) == d)
        {
            printf("internally tangent\n");
        }
        else if (r1 + r2 == d)
        {
            printf("externally tangent\n");
        }
        else if (d > fabs(r1 - r2) && d < fabs(r1 + r2))
        {
            printf("overlap\n");
        }
    }
    return 0;
}
