9 - 15 行 复制粘贴 带进来中文的或者它编码的 空格、等 空白字符 请删一删

使用了中文输入法的问题吧

没有用，原来的
float sn=100.0,hn=sn/2;
int n;
for(n=2;n<=10;n++)
　{
　　sn=sn+2*hn;/*第n次落地时共经过的米数*/
　　hn=hn/2; /*第n次反跳高度*/
　}
printf("the total of road is %f\n",sn);
printf("the tenth is %f meter\n",hn);
也是报错...

没啊，书里给出的代码例子，也是报错，我只是把输出的部分换成了中文而已，代码都没改

你的代码里面有全角符号。换成半角符号就没问题了。
float sn=100.0,hn=sn/2;
int n;
for(n=2;n<=10;n++){
sn=sn+2*hn;/*第n次落地时共经过的米数*/
hn=hn/2; /*第n次反跳高度*/
}
printf("the total of road is %f\n",sn);
printf("the tenth is %f meter\n",hn);

主函数都木有

3楼4楼正解

在输入法上面右键 然后属性 找到这个

谢谢，搞定了
