我的可以正常编译，但为什么会保存出错呢？位数较多的是我故意的，程序如下:
# include <stdio.h>
void main()
{
double shanghai=57.88;
double shanghaizengjia=4.5;
double gongjijuli=172;
double hujia=27.536;
double hujiazengjia=3.0;
double mokang=32.1;
double mokangzengjia=1.25;
double shengmingzhi=616;
double shengmingzhizengjia=84.25;
double shengminghuifu=7.84;
double shengminghuifuzengjia=0.5;
double falizhi=0.0;
double falizhizengjia=0.0;
double falihuifu=0.0;
double falihuifuzengjia=0.0;
double yisu=340;
double dianquan=450;
double jinbi=1000;
printf ("英雄名称:德玛西亚.盖伦\n");
printf ("伤害:%.2lf(+%.1lf)\t攻击距离:%.0lf\n",shanghai,shanghaizengjia,gongjijuli);
printf ("护甲:%.3lf(+%.1lf)\t魔抗:%.1lf(+%.2lf)\n",hujia,hujiazengjia,mokang,mokangzengjia);
printf ("生命值:%.0lf/t(+%lf)\t生命回复:%lf(+%lf)\n",shengmingzhi,shengmingzhizengjia,shengminghuifu,shengminghuifuzengjia);
printf ("法力值:%.1lf(+%.1lf)\t法力回复:%.1lf(+%.1lf)\n",falizhi,falizhizengjia,falihuifu,falihuifuzengjia);
printf ("移速:%lf\t定位:上单 辅助 打野\n",yisu);
printf("点券:%lf\t金币:%lf\n",dianquan,jinbi);
}

重开，试试
