struct nodeS * headS=(struct nodeS*)malloc(SN);这一句 调用了函数malloc 看你的写法 headS应该是全局变量 全局变量定义的时候是不能调用函数的 只能在其他函数中为其初始化 可以这样 struct nodeS * headS;int main(){ headS=(struct nodeS*)malloc(SN);...} 是否有问题？ 有问题请追问 没问...
I use a class with a const constructor with new and it complains that it is not a constant expression even though none should be required. I'm also pretty sure I didn't make changes related to this code since a few months and it worked s...
中间case 里有个问题，一个=是赋值 当然，关键是 case 后面一个是一种值吧 你这个 有 if else 就可以
下面的语句（第4行）有错：u16 rr=uy;错误的原因是定义变量的初始化值必须是常数，不能是变量，你可以修改为：u16 rr=9;
