  • Q6. Copy constructor?
  • Q7. Different types of polymorphism, the diamond problem, and how can it be avoided?
  • Ans. 

    Polymorphism refers to the ability of an object to take on many forms. The diamond problem occurs in multiple inheritance.

    • Polymorphism can be achieved through method overloading and method overriding.

    • Method overloading allows multiple methods with the same name but different parameters.

    • Method overriding occurs when a subclass provides a specific implementation of a method already defined in its superclass.

  • Q9. Template classes
  • Q10. Write a program for an operator(=) such that it behaves differently for integer and character
  • Ans. 

    The program should differentiate between integers and characters when using the assignment operator (=).

    • Check the data type of the variable before assigning a value.

    • Use conditional statements to perform different actions based on the data type.

    • For integers, assign the value directly. For characters, convert the character to its ASCII value and assign it.

  • Q13. When to use List and Vector of Standard Template Library ?
  • Ans. 

    List is preferred when frequent insertion and deletion is required. Vector is preferred when random access is required.

    • List is implemented as a doubly-linked list, allowing for efficient insertion and deletion at any position.

    • Vector is implemented as a dynamic array, allowing for efficient random access.
