just define a string border(20,'#') and cout it before and after the sides:

C++

#include <iostream>
#include <string>
using namespace std;
 int main( void )
 {
     string border( 20, '#');
     string spaces( 20, ' ' );
     cout<< '#' << border << "#\n";
     cout<< '#' << spaces << "#\n";
     cout<< '#' << spaces << "#\n";
     cout<< '#' << spaces << "#\n";
     cout<< '#' << spaces << "#\n";
     cout<< '#' << border << "#\n";
     system("pause");
     return 0;
 }

But now try to understand this:

C++

#include <string>
#include <iostream>
int main()
{
    static const int WIDTH=18;
    static const int HEIGHT=8;

    std::string border(WIDTH-2,'#');
    std::string spaces(WIDTH-2,' ');
    std::cout << '#' << border << '#' << std::endl;
    for(unsigned int i=1; i<HEIGHT-1; ++i)
    {
        std::cout << '#' << spaces << '#' << std::endl;
    }
    std::cout << '#' << border << '#' << std::endl;

    system("pause");
    return 0;
}

Do you understand the use of constants and of the control structures ?!?
