a variable that can store a
temperature rounded to the
nearest tenth of a degree?




A teacher determines student C. int totalPoints; double
percentages in a course as the percentage;
points a student earns divided by
the total points available in the
grading period. Points are awarded
only in whole number increments,
but student percentages are to be
stored as decimals.
The following code segment
appears in a program used to
compute student percentages.
Points that a student earns are
stored in pointsEarned, the total
points available in the grading
period are stored in totalPoints, and
the student percentage is stored in
percentage.
int pointsEarned;

appropriate to replace / missing
code / in the program?
