主要注意格式，每个case之后都有一个空行~~

#include <iostream>using namespace std;int main(){int n,m;int i,j;while(cin>>n>>m){for(i=0;i<m+2;i++){if(i==0||i==m+1) cout<<"+";else cout<<"|";for(j=0;j<n;j++){if(i==0||i==m+1) cout<<"-";else cout<<" ";}if(i==0||i==m+1) cout<<"+"<<endl;else cout<<"|"<<endl;}cout<<endl;}return 0;}
