A teacher determines student percentages in a course as C. int totalPoints;
the points a student earns divided by the total points double percentage;
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;
/ missing code /

/ missing code / in the program?

,Consider the following code segment: D. The variable x should be declared as a double and the variable y should be
/ data type 1 / x = 0.5; declared as a boolean.
/ data type 2 / y = true;
Which of the following best describes the data types that
should be used to replace/ data type 1 / and / data type
2 / so that the code segment compiles without error?


Consider the following code segment. D. x + 1
int x;
int y;
x = 3;
y = / missing expression /;
