those are flags for your output. cout.setf is a function to set the flags

ios::fixed - Display floating point values using normal notation (as opposed to scientific)

ios::showpoint - Display a decimal and extra zeros, even when not needed.

cout.setprecision(4) is limiting the precision of your number to 4 decimal places. so if you had a double d = 3.14159 and you did a cout.setprecision(4) you would get 3.142

chinga tu madre|||i have no idea. I learned a lil bit of C++ 1 and half year ago. right now, I can remember nothing but "#include"|||hello!

setf means that you will set the flag. fixed means that to display real values in a fixed notation and showpoint is to display a trailing decimal point and trailing decimal zeros when real numbers are displayed. and last precision means you set the output into 4 decimal places.

hope that would help. God bless! =)
