Quizplus · Accepted Answer

The statement uses the setw manipulator to set the field width to 4, which means that it will allow four spaces for the value stored in the variable num4. Therefore, option A is true. Option B and D are incorrect because the statement does not output or input anything other than the value stored in num4. Option C is false because there is no variable named num10 in the statement. Therefore, the correct choice is A.
