Q21. Which of the following is an example of a procedural programming language?
a) C
b) Java
c) Python
d) Ruby
Show Answer
Correct Answer: a) C
Explanation: C is an example of a procedural programming language, which focuses on a step-by-step approach to problem-solving using procedures or functions. Procedural languages are characterized by their structured programming techniques and the use of control structures like loops and conditionals. Some more examples of Procedural languages are FORTRAN, COBOL, ALGOL, BASIC and Pascal.
Q22. What is the primary purpose of a linker in the programming process?
a) To execute the program
b) To translate the source code into machine code
c) To check the syntax of the source code
d) To combine object files and resolve references between them
Show Answer
Correct Answer: d) To combine object files and resolve references between them
Explanation: The primary purpose of a linker is to combine object files generated by a compiler and resolve references between them to create an executable file. It ensures that all the required libraries and functions are linked correctly to the final executable.
Q23. Which of the following is an example of a machine language?
a) Binary code
b) Assembly language
c) C++
d) Python
Show Answer
Correct Answer: a) Binary code
Explanation: Machine language, also known as binary code, is the lowest-level programming language that consists of a sequence of binary digits (0s and 1s). It is directly executed by the computer’s processor without the need for any translation.
Q24. What is the primary disadvantage of using a low-level programming language over a high-level programming language?
a) Low-level languages are slower
b) Low-level languages are more difficult to learn and use
c) Low-level languages are less secure
d) Low-level languages have limited graphics capabilities
Show Answer
Correct Answer: b) Low-level languages are more difficult to learn and use
Explanation: The primary disadvantage of using a low-level programming language over a high-level programming language is that low-level languages are more difficult to learn and use. They are closer to machine language and provide less abstraction, which makes them less convenient for programmers.
Q25. Which of the following is an example of a high-level programming language?
a) Machine language
b) Assembly language
c) Python
d) Binary code
Show Answer
Correct Answer: c) Python
Explanation: Python is an example of a high-level programming language that provides a higher level of abstraction and is easier to learn and use than low-level languages like machine language or assembly language.
Q26. What is the primary advantage of using a high-level programming language over a low-level programming language in terms of code portability?
a) High-level languages are faster
b) High-level languages are easier to learn and use
c) High-level languages are more portable across different platforms
d) High-level languages have better graphics capabilities
Show Answer
Correct Answer: c) High-level languages are more portable across different platforms
Explanation: The primary advantage of using a high-level programming language over a low-level programming language in terms of code portability is that high-level languages are more portable across different platforms. High-level languages are designed to be independent of specific computer architectures, which makes it easier to run the same code on different platforms with minimal modifications.
Q27. What is the primary purpose of an interpreter in the programming process?
a) To execute the program
b) To translate the source code into machine code during runtime
c) To check the syntax of the source code
d) To optimize the program’s performance
Show Answer
Correct Answer: b) To translate the source code into machine code during runtime
Explanation: The primary purpose of an interpreter is to translate the source code of a program written in a high-level programming language into machine code during runtime. Interpreters translate and execute the source code one line at a time, which allows for better error messages and easier debugging.
Q28. Which of the following is an example of a compiled programming language?
a) Python
b) JavaScript
c) C++
d) Ruby
Show Answer
Correct Answer: c) C++
Explanation: C++ is an example of a compiled programming language. Programs written in C++ are translated into machine code by a compiler before execution. Compiled languages typically offer better performance than interpreted languages, as the translation process is done only once, before the program is executed.
Q29. What is the primary disadvantage of using an interpreter over a compiler in terms of performance?
a) Interpreters are slower
b) Interpreters generate less efficient machine code
c) Interpreters require more memory
d) Interpreters provide less helpful error messages
Show Answer
Correct Answer: a) Interpreters are slower
Explanation: The primary disadvantage of using an interpreter over a compiler in terms of performance is that interpreters are generally slower. Since interpreters translate and execute the source code one line at a time during runtime, the translation process adds overhead to the execution, resulting in slower performance compared to compiled languages.
Q30. Which of the following is an example of an interpreted programming language?
a) C
b) Java
c) Python
d) Assembly language
Show Answer
Correct Answer: c) Python
Explanation: Python is an example of an interpreted programming language. Programs written in Python are translated into machine code by an interpreter during runtime. Interpreted languages offer better error messages and easier debugging, but they are generally slower than compiled languages due to the overhead of the translation process during execution.
