#1

#include
using namespace std;

int main()
{
int i, j, n;

cin>>n;


for(i=1; i<=n; i++)
{

    for(j=1; j<=n; j++)
    {
        if(i==1 || i==n||j==1||j==n||j==i||j==n-i+1)
        {

        cout<<"*";
        }
        else
        {
            cout<<" ";
        }
    }

    cout<<"\n";
}

return 0;

What you are doing is creating a box and then creating its diagonals.
Whereas we need to create box with * and a diamond in it with space. To create space you need to increase the spaces in each line till you reach mid height, then decrease space in each line. (Focus on mid height and width to keep track of spaces.)
