Question 40 Explanation:
→The conversion specifier %7.2f tells printf to display the value as a 7-character wide field with 2 digits following the decimal point.
→The %e format uses scientific notation, i.e. one digit before the decimal separator and an exponent for scaling
→The %e format uses scientific notation, i.e. one digit before the decimal separator and an exponent for scaling
Correct Answer: B
