Emphasized on functional programming, Clojure is a programming language that treats code as data. If you're starting to develop an interest, beginning to learn, or just want to know how it works, take this basic programming test.

Questions and Answers

1.

Clojure is based on which programming language?
- A.
  
  PHP
- B.
  
  Ruby
- C.
  
  Python
- D.
  
  Lisp
Correct Answer
D. Lisp

Explanation
Clojure is based on Lisp. Lisp is a programming language that was developed in the late 1950s and is known for its unique syntax and powerful macro system. Clojure, created by Rich Hickey in 2007, is a modern dialect of Lisp that runs on the Java Virtual Machine (JVM). It leverages the strengths of Lisp and provides seamless integration with Java, making it a popular choice for building scalable and concurrent applications.

Which of these platforms is not used to run Clojure?
- A.
  
  Java Virtual Machine
- B.
  
  Common Language Runtime
- C.
  
  HyperText Markup Language
- D.
  
  JavaScript
Correct Answer
C. HyperText Markup Language

Explanation
The correct answer is HyperText Markup Language. HTML is not a platform used to run Clojure. Clojure is primarily run on the Java Virtual Machine (JVM) and can also be run on the Common Language Runtime (CLR) and JavaScript platforms. HTML, on the other hand, is a markup language used for creating web pages and does not provide a runtime environment for running programming languages like Clojure.

Who designed Clojure?
- A.
  
  Rich Hickey
- B.
  
  James Borderman
- C.
  
  Huateng Xue
- D.
  
  Jerry Clojure
Correct Answer
A. Rich Hickey

Explanation
Rich Hickey is the correct answer because he is the creator and designer of the programming language Clojure. He developed Clojure with the goal of combining the benefits of functional programming with the practicality and efficiency of a dynamic language. Rich Hickey's expertise and vision in programming languages led to the creation of Clojure, which has gained popularity for its simplicity, concurrency features, and seamless integration with existing Java code.

Which of these is not a file extension for Clojure?
- A.
  
  Clj
- B.
  
  Cljs
- C.
  
  Ens
- D.
  
  Edn
Correct Answer
D. Edn

Explanation
The file extension "edn" is not a valid file extension for Clojure. Clojure files typically have the extensions "clj" for Clojure source code files and "cljs" for ClojureScript source code files. "ens" is not a recognized file extension for Clojure either.

How can you declare a variable in Clojure?
- A.
  
  (def var- name var- value )
- B.
  
  [def var- name var- value]
- C.
  
  {def var- name var- value}
- D.
  
  Def var- name var- value
Correct Answer
A. (def var- name var- value )

Explanation
In Clojure, a variable can be declared using the syntax (def var- name var- value). This statement defines a new variable with the specified name and assigns it the given value. The "def" keyword is used to declare a variable in Clojure. The variable name and value are enclosed in parentheses, with the name followed by the value.

Which of the following does Clojure use?
- A.
  
  Alphabets
- B.
  
  Positive integers
- C.
  
  Negative integers
- D.
  
  0 and 1
Correct Answer
B. Positive integers

Explanation
Clojure is a programming language that uses positive integers. This means that it supports the use of whole numbers that are greater than zero. Positive integers are commonly used in programming for various purposes such as counting, indexing, and performing mathematical operations. Clojure's use of positive integers allows developers to manipulate and work with numerical data in their programs.

How many types of Clojure maps exist?
- A.
  
  4
- B.
  
  3
- C.
  
  2
- D.
  
  1
Correct Answer
C. 2

Explanation
Clojure maps have two types: hash maps and sorted maps. Hash maps are the most commonly used type and store key-value pairs in an unordered manner. Sorted maps, on the other hand, store key-value pairs in a sorted order based on the keys. Therefore, the correct answer is 2.
