Programming Languages and Compilers Questions

Multiple choice

Which of the following is a low level language?

  1. Machine language

  2. C

  3. JAVA

  4. LISP

  5. COBOL
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A low level programming language is one that provides little or no abstraction from a computer's instruction set architecture. Generally, this refers to either machine code or assembly language.

Multiple choice

Which of the following models bridges the execution gap by translating a program written in a programming language called the source program into an equivalent program in the machine or assembly language of the computer system called the target program?

  1. Program Interpretation

  2. Program Translation

  3. Linear Search

  4. Binary Search

  5. Multiprogramming
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This model bridges the execution gap by translating a program written in a programming language called the source program into an equivalent program in the machine or assembly language of the computer system called the target program.

Multiple choice

Which of the following assembly language statements indicates an action to be performed during the execution of the assembled program?

  1. Imperative statement

  2. Declaration statement

  3. Assembler directives

  4. YACC

  5. Debugger
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is an assembly language statement which indicates an action to be performed during the execution of the assembled program. This is a language processor development tool which is a syntax directed definition for the translation of the source program into an IR or the target program.

Multiple choice

  1. Lexical Analysis

  2. Syntax Analysis

  3. Intermediate Code Generation

  4. Code Optimisation

  5. Code Generation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This phase of the compiler transforms the parse tree into an intermediate language representation of the source program called Three-Address Code.

Multiple choice

Which of the following system softwares is used in the process of replacing symbolic references or names of libraries with actual usable addresses in the memory before running a program?

  1. Loader

  2. Linker

  3. Object program

  4. Compiler

  5. Interpreter
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The process of replacing symbolic references or names of libraries with actual usable addresses in memory before running a program is called as relocation and is performed mainly by the linker.

Multiple choice

LISP stands for _____.

  1. List Progress

  2. List Processor

  3. List Progressive

  4. List Programming
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

LISP (List Processing) is a high-level programming language designed for symbolic computation and list manipulation. Its name directly reflects its core functionality - processing lists as the primary data structure.

Multiple choice

PROLOG stands for _____.

  1. Programming in Logic

  2. Programming for Listing

  3. Programming for Language

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

PROLOG (PROgramming in LOGic) is a logic programming language associated with artificial intelligence and computational linguistics. Its name directly indicates that it uses logic (declarative programming) rather than procedural imperative commands.
