100% Correct | Grade A
Section 1: Programming Languages and Paradigms
Question 1
A programming library is used to: (choose two)
A. improve productivity
B. add functionality related to a single purpose
C. replace the need for a compiler
D. execute code faster than native code
Correct Answer: A. improve productivity, B. add functionality related to a
single purpose
Rationale: Libraries provide pre-written code to improve
productivity and add specific functionality. They do not replace
compilers (C) or inherently execute faster than native code (D).
,Question 2
Which language type executes faster?
A. Interpreted language
B. Compiled language
C. Both execute at the same speed
D. Scripting language
Correct Answer: B. Compiled language
Rationale: Compiled languages are translated directly into machine
code, which executes faster than interpreted languages that are
translated line-by-line at runtime.
Question 3
Which language type is NOT written for a specific type of machine?
A. Compiled language
B. Interpreted language
C. Assembly language
D. Machine language
Correct Answer: B. Interpreted language
Rationale: Interpreted languages are platform-independent because
the interpreter handles the translation at runtime. Compiled
languages (A) are machine-specific. Assembly (C) and machine
language (D) are hardware-specific.
Question 4
Which languages are compiled?
A. C, C++, Java, C#
,B. Python, JavaScript, Ruby
C. HTML, CSS, XML
D. SQL, Bash, Perl
Correct Answer: A. C, C++, Java, C#
Rationale: C, C++, Java, and C# are compiled languages (Java is
compiled to bytecode). Python (B) is interpreted. HTML (C) is a
markup language. SQL (D) is a query language.
Question 5
Which languages support object-oriented principles?
A. Python
B. JavaScript
C. C#
D. MATLAB
E. C++
F. Java
G. All of the above
Correct Answer: G. All of the above
Rationale: All listed languages support object-oriented programming
to varying degrees.
Question 6
Which type of language cannot change a variable's type while running the
program?
A. Dynamically typed
B. Statically typed
, C. Loosely typed
D. Weakly typed
Correct Answer: B. Statically typed
Rationale: Statically typed languages require variable types to be
declared and fixed at compile time.
Question 7
Which type of language is considered easier to use?
A. Statically typed
B. Dynamically typed
C. Compiled
D. Assembly
Correct Answer: B. Dynamically typed
Rationale: Dynamically typed languages are often considered easier
because they don't require explicit type declarations.
Question 8
You create an integer variable and assign it a string value. When you run
the program you do not receive an error. What type of language are you
using?
A. Statically typed
B. Dynamically typed
C. Compiled
D. Assembly
