我有以下 C++ (它还没有真正做任何事情......)
#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;
}
当我运行它时,它会在 MS V C++ 中显示以下错误消息

这是为什么……Ranker后面不跟void?!?!
