请教大家一下这个程序那里错啦

Question

“circle.h”文件内容
class circle{
private:
int radius;
public:
virtual circle();
circle();
};
circle.cpp文件内容
#include “circle.h”
#include
using namespace std;
circle::circle()
{
cout<<"Here is constructor\n";
this->radius=6;
return radius;
}
void circle::circle()
{
cout<<"Here is destructor\n";
}

Answer 1

有什么报错提示吗，还有为什么那么多划掉的啊
析构函数些错了，应该改成circle::~circle()
return radius; //如果有报错的话可以改成return this->radius;
