私は次のC++を持っています(これはまだ実際には何もしていません...)
#include "stdafx.h"
#include <iostream>
using namespace std;
class Ranker
{
int up, down;
public:
void set_ranks(int, int);
int rank(int, int, int, double);
}
void Ranker::set_ranks(int a, int b)
{
up = a;
down = b;
}
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
実行すると、MS VC++で次のエラーメッセージが表示されます。

なぜこれが...ランカーの後にボイドが続かないのですか?!?!
