#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main()
{
   const int arm = 4;        // change back to 2 when desired
   int diam = 2 * arm + 1;
   vector<string> star( diam, string( diam, ' ' ) + '\n' );
   for ( int i = 0; i < diam; i++ ) star[i][i] = star[i][arm] = star[i][diam-1-i] = star[arm][i] = '*';
   for ( string s : star ) cout << s;
}

If you don't like std::string or std::vector ...

#include <iostream>
using namespace std;

int main()
{
   const int arm = 4;        // change back to 2 when desired
   int diam = 2 * arm + 1;
   for ( int i = 0; i < diam; i++ )
   {
      for ( int j = 0; j < diam; j++ ) cout << ( j == i || j == diam - 1 - i || i == arm || j == arm ? '*' : ' ' );
      cout << '\n';
   }
}
