Q1 Question 1 of 75
A 22-year-old computer science student is writing her first program and needs to understand
the basic building blocks of any algorithm. Her instructor explains that every algorithm must
have a finite number of well-defined steps that produce a result. This property of algorithms is
known as which of the following?
A. Recursion
B. Finiteness
C. Polymorphism
D. Inheritance
Correct Answer: B
Rationale:
Finiteness means an algorithm must terminate after a finite number of steps, which is a fundamental
property distinguishing algorithms from open-ended processes. Recursion is a technique where a function
calls itself, and polymorphism and inheritance are object-oriented programming concepts, not algorithm
properties.
Q2 Question 2 of 75
A software developer is designing a program to calculate the area of a rectangle. She writes
down the step-by-step process: first get the length, then get the width, then multiply them,
then display the result. This step-by-step representation is best described as which of the
following?
A. Source code
B. Pseudocode
C. Compiled bytecode
D. Machine language
Correct Answer: B
Rationale:
Pseudocode is an informal, human-readable description of an algorithm that uses plain language steps
without conforming to any specific programming language syntax. Source code is written in an actual
programming language, bytecode is compiled intermediate code, and machine language is binary
instructions the processor executes.

Q3 Question 3 of 75
A first-year programming student encounters a syntax error when compiling his Python
program. The error message indicates a missing colon at the end of an if statement. Which
phase of the programming process does this error belong to?
A. Design phase
B. Compilation phase
C. Testing phase
D. Deployment phase
Correct Answer: B
Rationale:
A syntax error is detected during the compilation (or interpretation) phase when the language processor
parses the source code and finds it does not conform to the grammar rules of the language. Design errors
are logic problems found during testing, and deployment happens after the code compiles and passes
testing.
Q4 Question 4 of 75
A junior developer is asked to trace through a program that adds the numbers 1 through 5
using a loop. She manually steps through each iteration, writing down the current value of the
sum variable after each step. This manual step-by-step execution is called which of the
following?
A. Compiling
B. Dry running or desk checking
C. Debugging with a debugger
D. Profiling
Correct Answer: B
Rationale:
Dry running or desk checking involves manually stepping through code line by line to trace variable values
and logic flow without actually executing the program on a computer. Compiling converts source code to
machine code, debugging uses automated tools, and profiling measures performance.

Q5 Question 5 of 75
A software engineering team follows the waterfall development methodology for a project. The
team lead emphasizes that each phase must be completed before the next begins. Which is
the correct sequence of phases in the waterfall model?
A. Coding, Design, Requirements, Testing, Maintenance
B. Requirements, Design, Coding, Testing, Maintenance
C. Testing, Requirements, Design, Coding, Maintenance
D. Maintenance, Testing, Coding, Design, Requirements
Correct Answer: B
Rationale:
The waterfall model follows a linear sequence starting with Requirements gathering, then Design, then
Coding (implementation), then Testing, and finally Maintenance. This sequential approach means each
phase must be completed before moving to the next, unlike agile methodologies that iterate.
Q6 Question 6 of 75
A student runs her program and receives an output of 25 when she expected 15 for a
calculation that should compute the average of 10 and 20. The program adds the two
numbers instead of dividing their sum by 2. What type of error does this represent?
A. Syntax error
B. Logic error
C. Runtime error
D. Compilation error
Correct Answer: B
Rationale:
A logic error occurs when a program runs without crashing but produces incorrect results because the
algorithm or formula is wrong. The program adds instead of averaging, which is a flaw in the program logic.
Syntax and compilation errors prevent the program from running, and runtime errors cause crashes.
