Answer 1

I just added this line in your code and the output shows with no problem:
cout << setprecision(3) << f;

C++ is case-sensitive!

C++ is backward compatible with C so you may also use printf() if you like.

Answer 2

For output you may use the setprecision(x) manipulator:
cout << setprecision(3) << value;

If you want to truncate the variable as in a bank operation than try this to truncate to two decimals:
value = round(value * 100.0) / 100.0;

Instead of cout<<e<<endl
Use printf("%.2f\n",e);
