int main()

{

 cout << "Join http://shapesinc.blogspot.com for more codes of shapes\n\n";

 cout<<"CAUTION:   The input should not be other than numerical values \n\n\a";
 

 int length=0;




 cout << "Enter the length of the hollow square\n";

 cin>>length;

 for(int i=0; i<length; i++)

 {

  for(int j=0; j<length; j++)

  {

   if(i==0 || i==length-1 || j==0 || j==length-1)

    cout << "*";

   else

    cout << " ";

  

  }

  cout<<endl;

 }

}

Output:
