Quizplus · Accepted Answer

The statement specifies a width of 4 for the output of the value in num4 using setw(4). This means that the value will be displayed using four spaces, regardless of its actual length. Option B is incorrect because setw(4) is not output, it is a function that sets the width of the output. Option C and D are incorrect because they offer incorrect values for the width specification.
