编写一个程序，递归调用成员函数，输出最大公约数

#include<iostream>
using namespace std;
class gcd_class
{
public:
    gcd_class(int p,int q);
    long func(int j,int k);
private:
    int n;
    int d;
};
gcd_class::gcd_class(int p,int q)
{
    n=p;
    d=q;
}
long gcd_class::func(int j,int k)
{
    if(k==0)
        return j;
    else return(k,j%k);
}
class derived:public gcd_class
{
protected:
    char *c;
public:
    derived(char *m):gcd_class(1,1)
    {
        c=m;
    }

    long pfunc(int l,int r)
    {
        return gcd_class::func(l,r);

    }


};
int main()
    {
        derived A("output n!\n");
        int n,d;
        cout<<"please input two int :";
        cin>>n>>d;
        cout<<"gcd("<<n<<","<<d<<")="<<A.pfunc(n,d)<<endl;
        return 0;
    }
