Programming Language Context
While CSC 126 focuses on foundational concepts applicable across languages, questions may reference common instructional
languages including Python, Java, C++, or pseudocode. Students should be prepared to interpret code snippets in a language-
agnostic manner, focusing on logic and structure rather than language-specific syntax variations.
Introduction & Answer Format
This CSC 126 Introduction to Computer Science Final Exam for the 2026/2027 academic cycle reflects comprehensive computer
science curriculum standards for undergraduate introductory programs. The examination evaluates foundational understanding of
programming principles, algorithmic thinking, data structures, problem-solving methodologies, and computational concepts
required for success in advanced computer science courses and software development pathways.
All correct answers must be presented in bold and green, followed by clearly defined, technically accurate rationales that reinforce
computer science principles, algorithmic logic, programming best practices, and computational thinking strategies.
Programming Fundamentals (Questions 1-14)
1. Which of the following is considered a low-level programming language directly executable by a computer's CPU
without a translator program?
A. Python
B. Java
C. Assembly Language
D. C++
Correct Answer: C. Assembly Language
Rationale: Assembly language is a low-level programming language that directly corresponds to the machine code instructions
of a particular computer architecture. It is typically translated into machine code by an assembler, which is a near one-to-one
mapping to CPU instructions.
, 2. What is the primary purpose of a 'compiler' in the software development process?
A. To execute a program line by line.
B. To translate source code directly into machine code before execution.
C. To manage memory allocation during runtime.
D. To identify and report syntax errors as they occur during typing.
Correct Answer: B. To translate source code directly into machine code before execution.
Rationale: A compiler translates an entire program's source code into executable machine code (or an intermediate bytecode)
before the program runs. This contrasts with an interpreter, which executes code line by line.
3. Consider the following pseudocode:
DECLARE num1 = 10
DECLARE num2 = 5
DECLARE result
result = num1 + num2 * 2
PRINT result
What is the predicted output?
A. 30
B. 20
C. 25
D. 15
Correct Answer: B. 20
Rationale: According to operator precedence (PEMDAS/BODMAS), multiplication is performed before addition. So, `num2 * 2` (5
* 2 = 10) is calculated first, then `10 + 10 = 20`.
