Q1 Question 1 of 75
A software developer is explaining the concept of algorithms to a new team member. She
describes an algorithm as a finite set of well-defined instructions that produces a result and
terminates after a specific number of steps. This definition emphasizes which fundamental
property of algorithms?
A. Finiteness
B. Determinism
C. Efficiency
D. Generality
Correct Answer: A
Rationale:
Finiteness is the property that an algorithm must terminate after a finite number of steps. Determinism
means each step has exactly one next step. Efficiency refers to resource usage. Generality means the
algorithm applies to a class of problems, not just one specific input.
Q2 Question 2 of 75
A programmer writes a flowchart that includes a diamond-shaped symbol at a decision point
where the process can follow two different paths. This diamond symbol represents which
programming concept?
A. A process or computation step
B. A decision or conditional branch
C. An input or output operation
D. A terminal start or end point
Correct Answer: B
Rationale:
In standard flowchart notation, a diamond shape represents a decision point where the flow can branch
based on a condition (true/false or yes/no). Rectangles represent processes, parallelograms represent
input/output, and ovals represent terminals (start/end).

Q3 Question 3 of 75
A student is learning about programming paradigms and encounters the term 'declarative
programming.' The instructor explains that in declarative programming, the programmer
describes what the program should accomplish rather than how to accomplish it. Which of
these is an example of a declarative approach?
A. Writing a loop that iterates through a list to find a maximum value
B. Writing a function that manually sorts an array using bubble sort
C. Writing a SQL query that selects records where age is greater than 30
D. Writing a recursive function to compute factorial
Correct Answer: C
Rationale:
SQL is a declarative language where you specify what data you want (records where age > 30) without
specifying how the database engine should retrieve it. The other options all describe the step-by-step
procedure (how), which is characteristic of imperative programming.
Q4 Question 4 of 75
A development team is discussing the software development life cycle. The team lead
explains that identifying what the software needs to do and documenting those requirements
happens before any code is written. This describes which phase?
A. Implementation phase
B. Testing phase
C. Maintenance phase
D. Requirements analysis phase
Correct Answer: D
Rationale:
Requirements analysis is the phase where the software's needed functionality is identified and documented
before coding begins. Implementation is writing the actual code. Testing verifies the code works correctly.
Maintenance involves updates after deployment.

Q5 Question 5 of 75
A programmer is tracing through a piece of pseudocode and encounters the expression: (5 +
3) * 2 - . Assuming standard order of operations, the result of this expression is
A. 14
B. 12
C. 16
D. 8
Correct Answer: A
Rationale:
Following the order of operations: first (5+3)=8, then 8*2=16, then 4/2=2, and finally 16-2=14. Multiplication
and division are evaluated left to right before subtraction. The parentheses force the addition to happen first.
Q6 Question 6 of 75
A programmer creates a variable naming convention where constants are written in
ALL_CAPS with underscores, such as MAX_RETRY_COUNT. This naming convention is
commonly used in many programming languages to indicate that a value
A. Should be stored in a database
B. Is a constant that should not be modified during program execution
C. Represents a global variable accessible from any function
D. Is a temporary variable used only within a single loop iteration
Correct Answer: B
Rationale:
The ALL_CAPS with underscores naming convention signals to other developers that the value is a constant
- a value that remains unchanged throughout program execution. This convention improves code readability
and helps prevent accidental modification of important fixed values.
