PROGRAMMING FOUNDATIONS FINAL
ASSESSMENT QUESTIONS WITH
VERIFIED ANSWERS AND DETAILED
EXPLANATIONS. 2026/2027
1. A developer is evaluating the expression ‘(x > 5) AND (y < 10 OR z == 7)’. If x = 6, y = 12, and
z = 7, what is the result of the expression?
A. Undefined
B. False
C. Null
D. True
Answer: D
Conceptual Explanation: Evaluating the expression: (6 > 5) is True. (12 < 10) is False, but
(7 == 7) is True. Thus, (False OR True) is True. Finally, (True AND True) results in True.
2. Which stage of the software development life cycle involves identifying the specific
features and constraints of a new software system?
A. Implementation
B. Analysis
,C. Design
D. Testing
Answer: B
Conceptual Explanation: The analysis phase focuses on understanding the user
requirements and defining what the system should do, including constraints and features.
3. What is the primary difference between a compiler and an interpreter?
A. A compiler executes code line-by-line, while an interpreter translates the whole program
first.
B. A compiler translates the entire source code into machine code before execution, while
an interpreter translates and executes it line-by-line.
C. Compilers are only used for low-level languages, while interpreters are for high-level
languages.
D. There is no difference; the terms are synonymous.
Answer: B
Conceptual Explanation: Compilers produce a standalone executable file by processing
the whole program at once, whereas interpreters process code on the fly.
4. In programming, what is a ‘logic error’?
A. An error where the program runs but produces incorrect or unexpected results.
B. An error that causes the program to crash immediately upon startup.
, C. An error that occurs when the code violates the rules of the programming language.
D. An error related to hardware failure during execution.
Answer: A
Conceptual Explanation: Logic errors occur when the program’s algorithm is flawed,
leading to incorrect output even though the code is syntactically correct.
5. Consider the following pseudocode: ‘Set x = 10; While x > 0: x = x - 3; Print x’. What is the
last value printed?
A. 1
B. -2
C. -1
D. 0
Answer: B
Conceptual Explanation: The loop iterations: x starts at 10. 10-3=7, 7-3=4, 4-3=1, 1-3=-2.
Since -2 is not > 0, the loop terminates after printing -2.
6. Which of the following data structures is most efficient for storing a fixed-size collection of
elements of the same type that can be accessed by an index?
A. Array
B. Linked List
C. Stack
