Programming Languages and Compilers Questions

Multiple choice

What is the difference between a compiler and an interpreter?

  1. A compiler translates the entire program into machine code before executing it, while an interpreter executes the program line by line.

  2. A compiler generates an intermediate code that is then executed by the operating system, while an interpreter directly executes the source code.

  3. A compiler is used for high-level languages, while an interpreter is used for low-level languages.

  4. A compiler is typically slower than an interpreter, but the resulting code is more efficient.

A Correct answer
Explanation

A compiler translates the entire program into machine code before executing it, while an interpreter reads and executes the program line by line.

Multiple choice

What is the purpose of a programming language syntax in a programming language?

  1. To define the rules and conventions for writing a program in a specific programming language.

  2. To allow a program to be parsed and interpreted by a compiler or interpreter.

  3. To improve the readability and understandability of a program.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A programming language syntax is a set of rules and conventions for writing a program in a specific programming language. It allows a program to be parsed and interpreted by a compiler or interpreter. It also improves the readability and understandability of a program.

Multiple choice

  1. C++

  2. Java

  3. Python

  4. InkScript
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Multiple choice

Which of the following is NOT a type of finite automaton?

  1. Deterministic Finite Automaton (DFA)

  2. Non-Deterministic Finite Automaton (NFA)

  3. Pushdown Automaton (PDA)

  4. Linear Bounded Automaton (LBA)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pushdown Automata are not finite automata, as they have a stack memory that allows them to remember previous states.

Multiple choice

Which of the following is NOT a type of context-free grammar?

  1. Chomsky Normal Form (CNF)

  2. Greibach Normal Form (GNF)

  3. Regular Grammar

  4. Context-Sensitive Grammar
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Regular grammars are not context-free grammars, as they have productions that can only generate strings of a certain length.

Multiple choice

Which of the following is NOT a type of Turing machine?

  1. Deterministic Turing Machine (DTM)

  2. Non-Deterministic Turing Machine (NTM)

  3. Universal Turing Machine (UTM)

  4. Linear Bounded Automaton (LBA)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Linear Bounded Automata are not Turing machines, as they have a limited amount of memory.

Multiple choice

Which of the following is NOT a type of language?

  1. Regular Language

  2. Context-Free Language

  3. Context-Sensitive Language

  4. Recursively Enumerable Language
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Recursively Enumerable Languages are not a type of language in the Chomsky Hierarchy.

Multiple choice

Which of the following is NOT a type of parsing?

  1. Top-Down Parsing

  2. Bottom-Up Parsing

  3. Left-to-Right Parsing

  4. Right-to-Left Parsing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Left-to-Right Parsing is not a type of parsing, as it is not a complete parsing strategy.

Multiple choice

Which of the following is NOT a type of language technology?

  1. Machine Translation

  2. Speech Recognition

  3. Natural Language Processing

  4. Optical Character Recognition
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Optical Character Recognition (OCR) is a technology that converts scanned images of printed or handwritten text into machine-encoded text, making it searchable and editable. It is not a language technology as it does not involve the understanding or processing of language.

Multiple choice
