20 Questions

  • Q1. How the operating system taking care of const int i=5; //tell the implementation so that we can't alter the value of i?
  • Ans. 

    Operating system uses memory protection to prevent modification of const variables like const int i=5;

    • Operating system marks the memory page containing i as read-only

    • Any attempt to modify i will result in a segmentation fault

    • Compiler may optimize code by replacing i with its value at compile time

  • Answered by AI
  • Q2. Explain the memory layout of main memory of computer system? Give an example to make understand the memory layout means in which segment what type of variable will be store?
  • Ans. 

    Explanation of memory layout in main memory of computer system.

    • Main memory is divided into four segments: stack, heap, data, and code.

    • Stack stores local variables and function calls.

    • Heap stores dynamically allocated memory.

    • Data stores global and static variables.

    • Code stores the program instructions.

    • Example: int x; //stored in data segment, int *p = new int; //stored in heap segment

  • Q3. By how many method we can allocate the memory in C and what is the difference between malloc and calloc. And which is faster and why?
  • Ans. 

    Two methods to allocate memory in C are malloc and calloc. Malloc allocates memory block of given size while calloc initializes the allocated memory block to zero.

    • Malloc allocates memory block of given size while calloc initializes the allocated memory block to zero.

    • Malloc returns a pointer to the first byte of allocated memory block while calloc returns a pointer to the first byte of initialized memory block.

    • Malloc is...

  • Answered by AI
  • Q4. Implementation of new() in C++?
  • Ans. 

    new() is an operator in C++ used for dynamic memory allocation.

    • new() returns a pointer to the allocated memory.

    • It can be used to allocate memory for primitive data types, arrays, and objects.

    • Memory allocated using new() must be deallocated using delete operator.

    • Example: int *ptr = new int;

    • Example: int *arr = new int[10];

    • Example: MyClass *obj = new MyClass();

  • Answered by AI
  • Q5. What is the difference between malloc and new and which one is faster and why?
  • Ans. 

    malloc and new are used to allocate memory dynamically. Malloc is faster but new is safer.

    • malloc is a C function while new is a C++ operator

    • malloc only allocates memory while new also initializes the memory

    • new throws an exception if allocation fails while malloc returns NULL

    • malloc is faster because it does not involve constructor calls

    • new is safer because it ensures type safety and prevents memory leaks

  • Answered by AI
  • Q6. Difference between extern and static and give an example to justify?
  • Ans. 

    extern and static are storage classes in C programming language.

    • extern is used to declare a variable or function that is defined in another file or module.

    • static is used to declare a variable or function that is local to a file or module.

    • Example of extern: extern int count; //declares count variable defined in another file.

    • Example of static: static int count = 0; //declares count variable local to the file.

  • Answered by AI
  • Q7. Is it possible to access the static variable defined in another file, if yes then how?
  • Q8. What is the difference between these two statement: const int *p; int const *p;
  • Ans. 

    The two statements are equivalent and declare a pointer to a constant integer.

    • Both statements declare a pointer to an integer that cannot be modified through the pointer.

    • The 'const' keyword can be placed before or after the 'int' keyword.

    • The pointer itself can still be modified to point to a different integer.

    • Example: const int *p; and int const *p; both declare a pointer to a constant integer.

  • Answered by AI
  • Q9. For statement const int *p = 5, which is true from given below two statement: a) int a; p = &a; b) *p = 0
  • Ans. 

    Cannot modify value pointed by p, but can change the address it points to.

    • p is a pointer to a constant integer with value 5

    • a) is valid as p can point to a non-constant integer

    • b) is invalid as *p is a constant and cannot be modified

  • Answered by AI
  • Q10. What is the self referential structure, write an example of self referential structure?
  • Ans. 

    Self referential structure is a structure that contains a pointer to the same type of structure.

    • It allows a structure to reference itself within its own definition.

    • It is commonly used in linked lists, trees, and graphs.

    • Example: struct Node { int data; struct Node *next; };

    • Here, the Node structure contains a pointer to another Node structure.

  • Answered by AI
  • Q11. Difference between structure and union and what are the pros and cons of both?
  • Ans. 

    Structure and union are data structures in C language. Union stores only one value at a time while structure stores multiple values.

    • Structure is used to store different data types while union is used to store only one data type at a time.

    • Structure allocates memory for all its members while union allocates memory for only the largest member.

    • Structure is used when we want to store multiple values of different data types ...

  • Answered by AI
  • Q12. What is the structure byte padding and how does it form and depend? Is there any concept
  • Ans. 

    Structure byte padding is the insertion of unused bytes between structure members to align them in memory.

    • Padding is added to ensure that each member of a structure is aligned on a memory boundary that is a multiple of its size.

    • The amount of padding added depends on the size and alignment requirements of the members.

    • Padding can affect the size of a structure and the performance of code that uses it.

    • For example, a struc...

  • Q13. How do we know the linked list is a circular or not?
  • Ans. 

    To check if a linked list is circular, we can use Floyd's cycle-finding algorithm.

    • Floyd's cycle-finding algorithm uses two pointers, one moving at twice the speed of the other.

    • If the linked list is circular, the fast pointer will eventually catch up to the slow pointer.

    • If the linked list is not circular, the fast pointer will reach the end of the list and the algorithm will terminate.

  • Q14. What type of OS is Windows?
  • Ans. 

    Windows is a proprietary operating system developed by Microsoft.

    • Windows is a graphical user interface (GUI) based operating system.

    • It is designed to run on personal computers, servers, and mobile devices.

    • Windows has different versions such as Windows 10, Windows 8, Windows 7, etc.

  • Ans. 

    There are 6 types of CPU scheduling: FCFS, SJF, SRTF, Priority, Round Robin, and Multilevel Queue. Each has its own advantages and disadvantages.

    • FCFS (First-Come-First-Serve) - processes are executed in the order they arrive

    • SJF (Shortest-Job-First) - shortest job is executed first

    • SRTF (Shortest-Remaining-Time-First) - preemptive version of SJF

    • Priority - processes with higher priority are executed first

  • Answered by AI
  • Q18. Is there any ideal CPU scheduling possible? Justify your answer?
  • Ans. 

    No, there is no ideal CPU scheduling possible.

    • CPU scheduling is a complex problem with many variables.

    • Different scheduling algorithms are suited for different scenarios.

    • The ideal scheduling algorithm would depend on the specific system and workload.

    • For example, a real-time system would require a different scheduling algorithm than a batch processing system.

  • Q19. How to set the priority of any process in windows and in linux?
  • Ans. 

    To set process priority in Windows and Linux, use task manager and nice command respectively.

    • In Windows, open task manager, right-click on the process and select 'Set Priority'

    • In Linux, use the 'nice' command followed by the process name or ID and the priority level (values range from -20 to 19)

    • Higher priority levels mean the process will get more CPU time
