新手小白，不明白错的是什么意思，百度不到，翻译也不行
#include<iostream>
using namespace std;
class Clock{
    private:
        int h;
        int m;
        int s;
        public:
            Clock(){
                cout<<"无参构造函数"<
            
            }
};
错误：[Error] expected primary-expression before '}' token    就是不知道这究竟是什么意思，恳请各路大神给我一点指导意见。

把学习时间浪费在混坛上是傻瓜行为，更何况自己的水平连一两都没到。

哎，估计是楼主代码没发全
要不楼主不会因为一行代码
天崩地裂般的呐喊出
我要裂开了

回复 6楼 叶纤
是挺绝望的，不过楼主还算好的，至少把报错给打出来，像一些人发完代码就完事，坐收答案。。。

感觉楼上说的有点像我呀，我好像一次都没发过系统报错信息，不过我的问题贴大部分都是可以运行的，要不就是一行报错，给出一个长篇报错信息，表示还不如不发
