As of my last update in September 2021, "BCSL-21" appears to be a course code or subject related to practical sessions in some academic curriculum. The specific questions asked in a viva (oral examination) for this subject can vary depending on the institution and the curriculum being followed. However, I can provide you with a list of general viva questions that are often asked in practical exams related to computer science or programming courses. Keep in mind that these questions are meant to be general and may not directly relate to BCSL-21. Please check with your course instructor or institution for the most relevant and accurate information regarding your viva examination.
1. **Introduction to the Practical:**
- What is the purpose of BCSL-21 practical session in your curriculum?
- Explain the topics covered in BCSL-21 and their importance in computer science.
2. **Programming Concepts:**
- Define programming and its significance in computer science.
- Differentiate between a compiler and an interpreter.
- Explain the concept of data types and their importance in programming.
3. **Programming Language (E.g., C, C++, Java, etc.):**
- What programming language(s) did you use in BCSL-21?
- Describe the basic syntax of the language used in your practicals.
- How do you declare and use variables in the programming language?
4. **Control Structures:**
- Explain the use of loops (e.g., for, while) in programming.
- How do you use conditional statements (e.g., if-else) in your code?
- Provide an example of a switch-case statement in your programming language.
5. **Functions and Procedures:**
- What are functions (or procedures), and why are they used in programming?
- Describe how you define and call functions in the programming language.
- Explain the concept of function parameters and return values.
6. **Arrays and Pointers:**
- What is an array, and how is it useful in programming?
- How do you declare and access elements of an array in your language?
- Explain the concept of pointers and their role in programming.
7. **File Handling:**
- What is file handling, and why is it important in programming?
- How do you open, read, and write to files in your programming language?
- Discuss the file modes used for different file operations.
8. **Error Handling:**
- How do you handle errors in your programming code?
- Explain the concept of exceptions (if applicable) in your language.
9. **Debugging and Testing:**
- How do you debug and test your programs for errors?
- Describe the process of identifying and fixing errors in your code.
10. **Project Specific Questions:**
- Explain the functionality and features of your BCSL-21 project.
- Describe the challenges you faced during the project and how you overcame them.
- Discuss the technologies or tools used to develop your project.
Remember that these are generic viva questions and may not cover specific topics related to BCSL-21. It is essential to review your course materials thoroughly and consult with your instructor to prepare adequately for your viva examination. Good luck!
