Programming Languages and Compilers Questions

Multiple choice

Which of these includes a specification of the native commands implemented by a particular processor?

  1. High-level language

  2. Microcode

  3. Interrupt

  4. Computer organization

  5. Instruction set architecture
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

An instruction set, or instruction set architecture (ISA), is the part of the computer architecture related to programming, including the native data types, instructions, registers, addressing modes, memory architecture, interrupt and exception handling, and external I/O. An ISA includes a specification of the set of opcodes (machine language), and the native commands implemented by a particular processor.

Multiple choice

The C programs are converted into machine language using a/an ____________.

  1. assembler

  2. compiler

  3. interpreter

  4. operating system

  5. both 2 and 3
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A compiler reads the entire program and converts it to the object code. It provides error, not of one line but error of the entire program. It takes more time for converting the lengthy programs. So this option is correct.

Multiple choice

By which language were first computers programmed?

  1. Machine language

  2. Assembly language

  3. Object code

  4. Source code

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

Yes, it is correct. Machine code or machine language is a set of instructions executed directly by a computer's central processing unit (CPU).

Multiple choice

What is common between a logic programming language and a functional language?

  1. Both are procedural

  2. Both are based on lambda calculus

  3. Both are declarative

  4. Both use Horn Clause

  5. Both are imperative
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Declarative programming is a non-imperative style of programming in which programs describe their desired results without explicitly listing commands or steps that must be performed. Functional and logical programming languages are characterized by a declarative programming style.

Multiple choice

In which grammars, productions permit arbitrary substitution of string during derivation or reduction, hence they are not relevant to specification of programming languages?

  1. Type-1 grammars

  2. Type-0 grammars

  3. Type-2 grammars

  4. Left regular grammars

  5. Right regular grammars
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Their productions permit arbitrary substitution of string during derivation or reduction, hence they are not relevant to specification of programming languages.

Multiple choice

Which language can be picked for writing a compiler?

  1. Assembly

  2. FORTRAN

  3. C

  4. JAVA

  5. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Writing a compiler requires modular and structured functions to execute compiler operations. One may also require to access the hardware directly, so such facility is required in the language. The language must also provide facility to handle complex data bases and structures with ease. C language provides all such facilities. So, it will be picked.
