求c++大神，友元类，代码如下

#include
#include
#include
using namespace std;

class interviewee
{
public:
friend class interviewer;
interviewee(string ming1,int age1,string job1)
{
ming=ming1;age=age1;job=job1;
}
interviewee(){}
friend showinfo(interviewee a)
{
cout<<a.ming<<"\t"<<a.age<<"\t"<<a.job<<endl;
}
private:
string ming,job;
int age;
};

class interviewer
{
public:
void getinfo(interviewee v)
{
vi.ming=v.ming;vi.age=v.age;vi.job=v.job;
}
void showinfo()
{
cout<<vi.ming<<" "<<vi.age<<" "<<vi.job;
}
private:
interviewee vi;
};

void main()
{
interviewee iv1("李依依",20,"路测工程师");
showinfo(iv1) ;
interviewer s;
interviewer.getinfo(iv1);
interviewer.showinfo();
}

有错误error C2143: syntax error : missing ';' before '.'
怎么改呢？

interviewer.getinfo(iv1);
interviewer.showinfo();

改为

s.getinfo(iv1);
s.showinfo();
