  • Answered by AI
  • Q19. Is HTTP a stateless or stateful protocol?
  • Ans. 

    HTTP is a stateless protocol.

    • HTTP is stateless because it does not retain any information about previous requests or responses.

    • Each request is treated as an independent transaction, and the server does not maintain any knowledge of the client's state.

    • To maintain state, cookies or session management techniques can be used.

    • Statelessness allows for scalability and simplicity in web applications.

  • Q21. What motivates me in life?
  • Q22. Explain the alignment issues in structures
  • Ans. 

    Alignment issues in structures occur due to memory padding and alignment requirements.

    • Structures may have unused memory space due to alignment requirements.

    • Padding is added to align structure members on memory boundaries.

    • Alignment issues can lead to wasted memory and decreased performance.

    • Compiler directives like #pragma pack can be used to control alignment.

    • Example: struct MyStruct { char a; int b; char c; };

  • Q26. I was asked in detail the concept of type casting in C
  • Q27. Can I declare a structure called ‘a’ which contains a structure called ‘b’ and ‘b’ in turn contains ‘a’?
  • Ans. 

    Yes, it is possible to declare a structure 'a' that contains a structure 'b' and 'b' in turn contains 'a'.

    • To achieve this, we can use forward declaration of one of the structures.

    • By using a pointer or reference to the other structure inside the first structure, we can avoid recursive definition.

    • This allows us to create a nested structure hierarchy.

  • Answered by AI
  • Q28. How do I find the offset of a member of a structure object? How would I do the same if I am not allowed to create the object at all?
  • Ans. 

    To find the offset of a member of a structure object, use the 'offsetof' macro. If not allowed to create the object, use 'sizeof' and pointer arithmetic.

    • Use the 'offsetof' macro to find the offset of a member within a structure object

    • If not allowed to create the object, use 'sizeof' to get the size of the structure and perform pointer arithmetic
