1. A car drove 200 miles using 10 gallons of fuel. Which operation should be
used to compute the miles per gallon, which is 20?
A. Addition
B. Subtraction
C. Multiplication
D. Division
Correct Answer =D. Division
*Explanation: Miles per gallon is calculated by dividing the total miles traveled by
the number of gallons used. The equation is 200 miles ÷ 10 gallons = 20 miles per
gallon. Addition, subtraction, and multiplication would not yield the correct result
for this calculation .*
2. A variable should hold a person's height in meters. Which data type should
the variable be?
A. Integer
B. Float
C. String
D. Boolean
Correct Answer =B. Float
*Explanation: Height in meters typically includes fractional values (e.g., 1.75
meters). Floating-point data types are designed to store numbers with decimal
,places. Integers store whole numbers only, strings store text, and Booleans store
true/false values .*
3. A variable should hold the names of all past U.S. presidents. Which data type
should the variable be?
A. Integer array
B. Float array
C. String array
D. Boolean array
Correct Answer =C. String array
Explanation: A collection of names requires a data type capable of storing multiple
text values. A string array is an ordered list that can hold multiple string elements.
Integers store numbers, floats store decimals, and Booleans store true/false .
4. A program uses the number of seconds in a minute in various calculations.
How should the item that holds the number of seconds in a minute be declared?
A. Constant float userTime
B. Variable float userTime
C. Constant integer secondsPerMinute
D. Variable integer secondsPerMinute
Correct Answer =C. Constant integer secondsPerMinute
Explanation: The number of seconds in a minute (60) is a fixed, unchanging value,
making it a constant rather than a variable. Descriptive names like
"secondsPerMinute" improve code readability. Integers are appropriate because
the value is a whole number .
5. A program determines if a user's age is high enough to run for U.S. president.
The minimum age requirement is 35. How should the item that holds the
minimum age be declared?
,A. Variable integer votingAge
B. Constant integer minAge
C. Constant float minAge
D. Variable string minAge
Correct Answer =B. Constant integer minAge
Explanation: The minimum age requirement (35) is a fixed value that should not
change during program execution, making it a constant. Integers are appropriate
for age values. Descriptive names like "minAge" clarify the purpose of the constant
.
6. Given integer x = 3 and integer y = 5. What is the value of the expression (x /
2.0) + y?
A. 5.0
B. 6.0
C. 6.5
D. 7.5
Correct Answer =C. 6.5
*Explanation: When an integer is divided by a floating-point number (2.0), the
operation performs floating-point division rather than integer division. 3 ÷ 2.0 =
1.5. Adding y (5) yields 6.5. Integer division (3/2) would truncate to 1, but the
presence of 2.0 forces floating-point arithmetic .*
7. Given float x = 10.2 and float y = 1.0. What is the value of the expression x /
y?
A. 0.0
B. 1.0
C. 10
D. 10.2
Correct Answer =D. 10.2
*Explanation: When both operands are floating-point numbers, division yields a
, floating-point result that preserves decimal values. 10.2 ÷ 1.0 = 10.2 exactly. The
result retains the precision of the original numbers .*
8. What kind of operator is the == in the expression i == 20?
A. Assignment
B. Arithmetic
C. Equality
D. Logical
Correct Answer =C. Equality
*Explanation: The == operator compares two values to determine if they are
equal, returning true or false. This distinguishes it from the assignment operator
(=), which stores a value. Arithmetic operators (+, -, , /) perform calculations, and
logical operators (&&, ||, !) combine Boolean expressions .
9. What is the purpose of parentheses () in a programming expression?
A. To print expressions
B. To group expressions
C. To run expressions
D. To compose expressions
Correct Answer =B. To group expressions
Explanation: Parentheses control the order of operations in an expression by
specifying which calculations should be performed first, similar to their use in
mathematics. They override default operator precedence rules to ensure
expressions evaluate correctly .
10. Given float x = 3.0. Which expression evaluates to 2.0?
A. x / 2
B. x / 2 + 0.
C. x / 2 + 0. + 0.25
D. x / 2 - 0.5
