fprintf

%4.2f in the formatSpec input specifies that the first value in each line of output is a floati­ng-­point number with a field width of four digits, including two digits after the decimal point. %8.3f in the formatSpec input specifies that the second value in each line of output is a floati­ng-­point number with a field width of eight digits, including three digits after the decimal point. n is a control character that starts a new line.
