Q11. What is the primary purpose of a flowchart in computer programming?
a) To debug the program
b) To provide a visual representation of the program’s logic
c) To write the program in a specific programming language
d) To optimize the program’s performance
Show Answer
Correct Answer: b) To provide a visual representation of the program’s logic
Explanation: The primary purpose of a flowchart in computer programming is to provide a visual representation of the program’s logic, which helps in understanding the flow of the process and the steps involved in solving a problem.
Q12. Which of the following flowchart symbols represents a process?
a) Circle
b) Rectangle
c) Diamond
d) Parallelogram
Show Answer
Correct Answer: b) Rectangle
Explanation: In a flowchart, the rectangle symbol is used to represent a process or an operation that needs to be performed.
Q13. What is the main advantage of using a flowchart in the development process?
a) It makes the program run faster
b) It helps in better communication and understanding of the problem
c) It automatically generates the source code
d) It reduces the need for documentation
Show Answer
Correct Answer: b) It helps in better communication and understanding of the problem
Explanation: The main advantage of using a flowchart in the development process is that it helps in better communication and understanding of the problem. It provides a visual representation of the algorithm, which makes it easier for the team members to understand the logic and collaborate effectively.
Q14. Which of the following is a limitation of using flowcharts?
a) They are difficult to create
b) They cannot represent complex algorithms
c) They are not suitable for large programs
d) They do not provide any documentation
Show Answer
Correct Answer: c) They are not suitable for large programs
Explanation: One of the limitations of using flowcharts is that they are not suitable for large programs, as they can become too complex and difficult to understand. For large programs, other methods like pseudocode or structured programming techniques are more appropriate.
Q15. What is the main difference between a flowchart and pseudocode?
a) Flowcharts use symbols, while pseudocode uses text
b) Flowcharts are used for debugging, while pseudocode is used for documentation
c) Flowcharts are a type of programming language, while pseudocode is a type of computer hardware
d) Flowcharts are used for system programming, while pseudocode is used for application programming
Show Answer
Correct Answer: a) Flowcharts use symbols, while pseudocode uses text
Explanation: The main difference between a flowchart and pseudocode is that flowcharts use symbols to represent the steps in an algorithm, while pseudocode uses text in a combination of natural language and programming constructs. Both flowcharts and pseudocode are used to describe the logic of an algorithm without the need for a specific programming language.
Q16. What is the primary purpose of a compiler 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 optimize the program’s performance
Show Answer
Correct Answer: b) To translate the source code into machine code
Explanation: The primary purpose of a compiler is to translate the source code of a program written in a high-level programming language into machine code, which can be executed by the computer’s processor.
Q17. Which of the following is an example of an object-oriented programming language?
a) C
b) Fortran
c) Java
d) Assembly language
Show Answer
Correct Answer: c) Java
Explanation: Java is an example of an object-oriented programming language, which focuses on objects and their interactions. It uses the concepts of classes, objects, inheritance, polymorphism, and encapsulation to model real-world entities and their relationships.
Q18. What is the primary advantage of using an interpreter over a compiler?
a) Interpreters are faster
b) Interpreters provide better error messages
c) Interpreters generate more efficient machine code
d) Interpreters are easier to learn and use
Show Answer
Correct Answer: b) Interpreters provide better error messages
Explanation: The primary advantage of using an interpreter over a compiler is that interpreters provide better error messages. Since interpreters translate and execute the source code one line at a time during runtime, they can provide more specific and helpful error messages when an error is encountered.
Q19. Which of the following is a disadvantage of using a compiler over an interpreter?
a) Compilers are slower
b) Compilers generate less efficient machine code
c) Compilers require more memory
d) Compilers provide less helpful error messages
Show Answer
Correct Answer: d) Compilers provide less helpful error messages
Explanation: A disadvantage of using a compiler over an interpreter is that compilers provide less helpful error messages. Since compilers translate the entire source code into machine code before execution, they may not provide specific and helpful error messages when an error is encountered.
Q20. What is the primary purpose of an assembler in the programming process?
a) To translate assembly language code into machine code
b) To execute the program
c) To check the syntax of the source code
d) To optimize the program’s performance
Show Answer
Correct Answer: a) To translate assembly language code into machine code
Explanation: The primary purpose of an assembler is to translate assembly language code, which is a low-level programming language, into machine code that can be executed by the computer’s processor.
