我正在处理这个C++代码，但无法让它工作......见下文

无法让它工作...路障。。。。帮助？！？ 我是新手，正在尝试为Delco CC的C++课程编写游戏代码。 任何帮助将不胜感激。 当它运行时，它不会按预期循环，因此我无法继续编写游戏的其余部分。

#include<iostream>
#include<string>
using namespace std;
int findMap()
{
int space;
cout<<"|  1  |  2  |  3  |"<<endl;
cout<<"|_____|_____|_____|"<<endl;
cout<<"|  4  |  5  |  6  |"<<endl;
cout<<"|_____|_____|_____|"<<endl;
cout<<"|  7  |  8  |  9  |"<<endl;
cout<<"|     |     |     |"<<endl;
cout<<"What space is your map in?"<<endl;
cin>> space;
if (space == 4||8)
{
          cout<<"Nope! There's nothing in here."<<endl;
          return findMap;
          }
if (space == 5||6)
{
          cout<<"Tough luck, you only found blank map paper. It's
useless."<<endl
          return findMap;
          }
if (space == 1||7)
{
          cout<<"You found poision gas. You failed."<<endl;
          return 0;
          }
if (space == 1)
{
          cout<<"Yippie! You found your map!"<<endl;
          }
if (space == 9)
{
          cout<<"Well, you found your wallet..."<<endl;
          return findMap;
          }

}
int game(findMap)
{
string name;
int findMap;
cout<<"It appears that you have been lost at sea."<<endl;
cout<<"But don't worry, you'll only have to survive until you reach
land, for this round."<<endl;
cout<<"Anyways, why don't you tell me your name?"<<endl;
cin>> name;
cout<<"Well, "<< name<<", do yourself a favour and find your
map..."<<endl;
cout<<findMap<<endl;
}
