Interview Questionnaire 

6 Questions

  • Q1. References vs pointers
  • Ans. 

    References and pointers are both used to refer to memory locations, but references cannot be null and cannot be reseated.

    • Pointers can be null or uninitialized

    • Pointers can be reseated to point to a different memory location

    • References are automatically dereferenced

    • References cannot be used with arrays

    • Pointers can be used with arrays

  • Answered by AI
  • Q2. Where is it necessary to use references
  • Ans. 

    References are necessary when passing large objects to functions or when returning objects from functions.

    • When passing large objects to functions

    • When returning objects from functions

    • When working with complex data structures

    • When implementing operator overloading

    • When working with polymorphism

  • Answered by AI
  • Q3. Const pointers
  • Q4. Where to declare const pointers
  • Ans. 

    Const pointers should be declared in the same scope as the variable they point to.

    • Declaring const pointers in the same scope as the variable they point to ensures that the pointer cannot be used to modify the variable.

    • If the pointer is only used within a function, it should be declared within that function.

    • If the pointer is used across multiple functions, it should be declared in a header file or at the top of the sour...

  • Answered by AI
  • Q5. Copy constructor with pointers
  • Ans. 

    Copy constructor with pointers creates a new object by copying the values of the existing object's pointers.

    • Copy constructor is used to create a new object from an existing object.

    • Pointers in the new object point to the same memory locations as the original object.

    • Deep copy should be used to avoid shallow copy issues.

  • Answered by AI
  • Q6. New vs malloc
  • Ans. 

    new and malloc are used for dynamic memory allocation in C++ and C respectively.

    • new is an operator in C++ while malloc is a function in C.

    • new automatically calls the constructor while malloc does not.

    • new returns a pointer to the object while malloc returns a void pointer.

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

    • new can be overloaded while malloc cannot be.

    • new and delete are used together wh

Experience: • 1 question was on time complexity of searching an unsorted array.
• 2 questions were on recursion, ie, number of recursive calls.
• 1 question on analysing given function on string.
• 1 question was on probability(Two hotels, say A and B. Probability of moving from A to B is 2/3, staying at A is 1/3. Probability of moving from B to A and staying at B is 1/2. If they make decisions each hour, and if they were at A at 7:00 pm, what is the probability that they will be at B at 10:00 pm).
• If a set has elements {1,2,3,4 .... n}. Then what is the sum of elements of it's power set. (Ex: S = {1,2}. Then power set is {{},{1},{2},{1,2}}. The sum is 6.
• If a set has elements {1,2,3,4,5,6,7,8,9,10}. Then how many subsets of 3 elements has no consecutive elements.
• 1 question was on designing a DFA for a string starting with a and ending with c and has at least b in it.
