How to print floating with 2 decimals using cout in C++

I only see how to do it using printf:

printf(" salary = %.2f" , salary) ;

But how to specify it in standard cout function? Do any coders know?

cout<< fixed <<setprecision(2)<< result<<endl ;

This is the right answer - fixed must be there!

Use cout.precision()

eg.

 int main ()
 {
 cout.precision(5);
 double i = 1.23556456123;
 cout << i;
 }
