10. Which of the following is a high-level programming language? 

a) Assembly

b) Machine language

c) C

d) Binary

Correct Answer: c) C
Explanation: C is a high-level programming language that is used for system programming and is easier for humans to read than low-level languages.

11. Which of the following is a low-level programming language? 

a) Java

b) Assembly

c) Pascal

d) Python

Correct Answer: b) Assembly
Explanation: Assembly language is considered a low-level programming language that is closer to machine code.

12. What is the main feature of a high-level language? 

a) It is machine dependent

b) It requires direct interaction with hardware

c) It is easy for humans to read and write

d) It is hard to debug

Correct Answer: c) It is easy for humans to read and write
Explanation: High-level languages are designed to be user-friendly and easier to understand compared to low-level languages.

13. What is the main feature of low-level languages? 

a) They are user-friendly

b) They are machine dependent

c) They are high-level

d) They are portable

Correct Answer: b) They are machine dependent
Explanation: Low-level languages are closely tied to the architecture of the hardware, meaning they are machine-dependent.

14. Which language is known as the first high-level programming language? 

a) Fortran

b) COBOL

c) C

d) Java

Correct Answer: a) Fortran
Explanation: Fortran (short for Formula Translation) was developed in the 1950s as one of the first high-level programming languages.

15. Which of these is an example of a low-level programming language? 

a) C

b) Assembly

c) Pascal

d) Python

Correct Answer: b) Assembly
Explanation: Assembly language is considered a low-level language as it directly corresponds to machine code instructions.

16. High-level languages are designed to be: 

a) Machine-specific

b) Portable

c) Hardware-dependent

d) Complex

Correct Answer: b) Portable
Explanation: High-level languages are platform-independent and portable, allowing programs to run on different types of machines with minimal modification.

17. The first version of the C programming language was developed by: 

a) Dennis Ritchie

b) James Gosling

c) Ken Thompson

d) Bjarne Stroustrup

Correct Answer: a) Dennis Ritchie
Explanation: Dennis Ritchie developed the C programming language at Bell Labs in the early 1970s.

18. Which of the following is a **language translator**? 

a) Compiler

b) Interpreter

c) Assembler

d) All of the above

Correct Answer: d) All of the above
Explanation: A compiler, interpreter, and assembler are all types of language translators, each converting high-level or assembly code into machine code in different ways.

19. Which of the following translates a high-level programming language into machine code in one go? 

a) Compiler

b) Interpreter

c) Assembler

d) None of the above

Correct Answer: a) Compiler
Explanation: A compiler translates the entire program written in a high-level language into machine code in one go, generating an executable file.

20. Which language is translated by an interpreter? 

a) Assembly language

b) High-level programming language

c) Machine code

d) Binary code
