(3 Questions)

  • Q1. Abput polymorphism? with code
  • Ans. 

    Polymorphism allows objects of different classes to be treated as objects of a common superclass.

    • Polymorphism allows for flexibility and reusability in code.

    • It enables a single interface to be used for different data types or classes.

    • Examples include method overriding in inheritance and method overloading within a class.

  • Answered by AI
  • Q2. STL MAPS? with code
  • Ans. 

    STL MAPS are associative containers that store elements formed by a combination of a key value and a mapped value.

    • STL MAPS are implemented as red-black trees for efficient searching, insertion, and deletion.

    • Elements in a map are always sorted based on the key value.

    • Example: std::map<int, string> myMap; myMap[1] = 'one';

(7 Questions)

  • Q1. Scope resolution with syntax ?
  • Ans. 

    Scope resolution refers to the process of specifying which scope a particular variable or function belongs to in a programming language.

    • Scope resolution is typically denoted by the double colon (::) operator in languages like C++ and PHP.

    • Example: ClassName::staticMember

    • Example: Namespace::functionName

  • Answered by AI
  • Q2. Template syntax?
  • Q3. Copy constructor and assignment operator?
  • Q4. V table and V pointer difference?
  • Ans. 

    V table is a table of function pointers used in object-oriented programming, while V pointer is a pointer to the V table.

    • V table is a table of function pointers used for dynamic dispatch in object-oriented programming.

    • V pointer is a pointer to the V table, allowing objects to call the correct functions at runtime.
