不要被3D图形迷了眼睛，其实他就是"+-|/ "这些字符的结合体。代码如下：

#include<iostream> using namespace std; int main(){ cout<<" +---+"<<endl; cout<<" / /|"<<endl; cout<<"+---+ |"<<endl; cout<<"| | +"<<endl; cout<<"| |/ "<<endl; cout<<"+---+"; return 0; }

#include<iostream> using namespace std; int main(){ cout<<" +---+"<<endl; cout<<" / /|"<<endl; cout<<"+---+ |"<<endl; cout<<"| | +"<<endl; cout<<"| |/"<<endl; cout<<"+---+"<<endl; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ cout<<" +---+"<<endl; cout<<" / /|"<<endl; cout<<"+---+ |"<<endl; cout<<"| | +"<<endl; cout<<"| |/"<<endl; cout<<"+---+"<<endl; return 0; }
