Set scientific flag when outputing double

  

#include <iostream>



using namespace std;



int main()

{

  int x = 100;

  double f = 98.6;

  double f2 = 123456.0;

  double f3 = 1234567.0;



  cout.setf(ios::scientific, ios::floatfield);

  cout << "After setting scientific flag:\n";

  cout << "f: " << f << "  f2: " << f2 << "  f3: " << f3 << endl;





  return 0;

}
