  • Q1. What is a virtual function in C++?
  • Ans. 

    A virtual function in C++ is a function that is declared within a base class and is redefined by a derived class.

    • Virtual functions allow a function to be overridden in a derived class.

    • They are used in polymorphism to achieve runtime binding.

    • The base class function must be declared as virtual for dynamic binding to occur.

    • Example: virtual void display() = 0; // pure virtual function

  • Q2. Can you explain the malloc() and free() operations in the context of memory management in C?
  • Ans. 

    malloc() is used to dynamically allocate memory in C, while free() is used to release allocated memory.

    • malloc() allocates a block of memory of specified size and returns a pointer to the beginning of the block.

    • free() deallocates the memory previously allocated by malloc() or calloc().

    • Example: int *ptr = (int*)malloc(5 * sizeof(int)); // Allocates memory for 5 integers

    • Example: free(ptr); // Deallocates the memory alloca

  • Answered by AI
  • Q3. What is structure padding?
  • Ans. 

    Structure padding is the concept of adding empty bytes to a structure to align its data members on memory boundaries.

    • Structure padding is done to optimize memory access and improve performance.

    • Padding is necessary because most processors require data to be aligned on specific memory boundaries for efficient access.

    • For example, if a structure contains a char followed by an int, padding may be added after the char to ali

  • Ans. 

    Bubble Sort algorithm is used to sort an array of non-negative integers in non-decreasing order.

    • Iterate through the array and compare adjacent elements, swapping them if they are in the wrong order.

    • Repeat this process until the array is sorted.

    • Time complexity of Bubble Sort is O(n^2) in worst case.

    • Space complexity of Bubble Sort is O(1) as it is an in-place sorting algorithm.

  • Ans. 

    Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.

    • Divide the input array into two halves recursively until each array has only one element.

    • Merge the sorted halves to produce a completely sorted array.

    • Time complexity of Merge Sort is O(n log n).

  • Q3. What is normalization in the context of database management systems?
  • Ans. 

    Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.

    • Normalization involves breaking down a database into smaller, more manageable tables.

    • It helps in reducing data redundancy by storing data in a structured way.

    • There are different normal forms such as 1NF, 2NF, 3NF, BCNF, etc., each with specific rules to follow.
