Quizplus · Accepted Answer

The method precision(n) sets the number of digits after the decimal point to be displayed in floating point values. This functionality is also provided by the stream manipulator setprecision(), which sets the same value for output streams. Therefore, choice C is the correct match for this scenario. The ostream class method precision(n) sets the number of digits to be displayed after the decimal point, which is equivalent to using the stream manipulator setprecision(). Therefore, the best choice is C. The other options (A, B, and D) are not equivalent to the precision(n) method.
