c++ - C++ - 使用代码块，类不能被访问

Question

代码不运行。我正在使用代码块。

我刚刚学会了如何创建类和访问它们，我是 C++ 新手

#include <iostream>
using namespace std;

class Bclass(){
    public:
        void print(){
            cout << "h" << endl;
        }
 };

int main(){
    Bclass c;
    c.print();
    return 0;
}


I expected the screen to print "h" but it didn't work.

Error results:

   /Users/jo/Desktop/classes/main.cpp|4|error: expected unqualified-id|

   /Users/jo/Desktop/classes/main.cpp|12|error: variable has incomplete type 'Bclass'|

   /Users/jo/Desktop/classes/main.cpp|4|note: forward declaration of 'Bclass'|

从类 BClass 的前面删除 ()。
