Change cout width and precision for string and float number output

  

#include <iostream>

using namespace std; 

int main(void)

{

   cout.precision(4);

   cout.width(10);

   cout << 10.12345 << endl;

   cout.width(10);

   cout.fill('-');

   cout << 10.12345 << endl;

   cout.width(10);

   cout << "Hi!" << endl;

   cout.width(10);

   cout.setf(ios::left);

   cout << 10.12345;

}
