s=s*10;
s=s+0.5;
s=(int)s;
s=s/10;
printf("s=%f\n",s);
}
这个程序怎么不能运行啊

#include mian() { double x,y,z,s; printf("input x,y,z:\n"); scanf("%lf %lf %lf",&x,&y,&z)#include mian(){ double x,y,z,s; printf("input x,y,z:\n"); scanf("%lf %lf %lf",&x,&y,&z); s=(x+y+z)/3; s=s*10; s=s+0.5; s=(int)s; s=s/10; printf("s=%f\n",s);}
恭喜你中奖了,第二行是：main(),您写错了
C是从main()函数开始编译连接的,如果没有编译器报错
最好写：
void main()
