使用c或c加加求解，如图所示

#include<bits/stdc++.h>
using namespace std;
int n;
int main(){
    cin>>n;
    for(int i=1;i<=n;i++){
        cout<<"  *"<<endl;
        cout<<endl;
        cout<<" * *"<<endl;
        cout<<endl;
        cout<<"*   *"<<endl;
        cout<<endl;
        cout<<" * *"<<endl;
        cout<<endl;
    }
    cout<<"  *";
    return 0;
}

最后面还少个*，
