Question

Consider the following code segments, which are each intended to convert grades from a 100-point scale to a 4 point scale and print the result. A grade of 90 or above should yield a 4.0, a grade of 80 to 89 should yield a 3.0, grade of 70 to 79 should yield a 20, and any grade lower than 70 should yield a 0.0 Assume that grade is an int variable that has been properly declared and initialized Code Segmenti double points = 0.0; ir (grade > 89) points 4.0; else if (grade > 79) points + 3.0; else if (grade > 69) points += 2.0; else points + 0.0; System.out.println (points); Code Segment II double points - 0.0; if (grade > 89) points + 4.0; if (grade > 79) grade 3.0; if (grade > 69) points - 2.0; if (grade points + 0.01 System.out.println (points); Which of the following statements correctly compares the values printed by the two methods? A. The two code segments print the same value only when grade is below 80. B. The two code segments print the same value only when grade is 90 or above or grade is below 80. C. The two code segments print the same value only when grade is 90 or above. D. Both code segments print the same value for all possible values of grade E. The two code segments print different values for all possible values of grade.

Answer 1

Answer:

A. The two code segments print the same value only when the grade is below 80.

Explanation:

The first code segment defines a nested if-else statement with the different grade categories to compare and print and would only print one value for a given grade range. The second code segment defines several if statements for each grade range and can add multiple values to the points variable for one grade range that meets the condition.

Both code segments would only print out the same values of points for a grade range below 80.
