Answer 1

#include <iostream>

using namespace std;


int main()

{

     intside,line=1,star=1,space=1,no_of_spaces,no_of_stars;


     cout << "Enter length of the side of the Octagon: ";

     cin >> side;


     cout << "\n\n";


     no_of_spaces = side;

     no_of_stars = side;


     for (line = 1; line <= side; line++){


           for (space = 1; space<no_of_spaces; space++)

                cout << " ";


           for (star = 1; star <= no_of_stars; star++)

                cout << "*";


           no_of_spaces--;

           no_of_stars += 2;


           cout << endl;

     }


     no_of_stars -= 2;


     for (line = 1; line<side; line++){


           for (star = 1; star <= no_of_stars; star++)

                cout << "*";


           cout << endl;

     }


     no_of_spaces = 1;

     no_of_stars -= 2;


     for (line = 1; line<side; line++){


           for (space = 1; space <= no_of_spaces; space++)

                cout << " ";


           for (star = 1; star <= no_of_stars; star++)

                cout << "*";


           no_of_spaces++;

           no_of_stars -= 2;


           cout << endl;

     }


     cout << "\n\n";

     return 0;
