解答:
main.cpp

#include <iostream>
#include <string>
#include "golf.h"
using namespace std;

#define SIZE 5

int main()
{
	golf ann;
	setgolf(ann, "AnnBirdfree", 24);
	golf andy;
	setgolf(andy);
	showgolf(ann);
	showgolf(andy);

	return 0;
}

golf.h

#pragma once

	char fullname[Len];//这是一个数组
	int handicap;
};


void setgolf(golf& g, const char* name, int hc);
