What is Virtual function in C++ // Hindi & English // C++ TUTORIAL

 

VIRTUAL FUNCTION IN C++


A C++ virtual function is a member function in the base class that you redefine in a derived class. It is declared using the virtual keyword.

It is used to tell the compiler to perform dynamic linkage or late binding on the function.


Virtual function का use हम जब करते जब हमें दो derive class के variable की एक ही copy लेना हों।


Bonus Learning—

  • Class data member और user define data होता है।
  • Class access करने के लिए हम object बनाते हैं।
  • हर data member अपने object की copy रखते हैं।

Dalton's Atomic Theory The theory that' all matter is made up of very tiny indivisible particles (atoms)' is called atomic theory of matter. Dalton's put forward his Atomic Theory of matter in 1808. The various postulates of Dalton's atoAto Theory of matter are as follows: All the matter is made up of very small particles called 'atoms'. Atoms cannot be divided. Atoms can neither be created nor destroyed Atoms are of various kinds. There are as many kinds of atoms as are elements. All the atoms of a given element are identical in every respect, having the same mass, size and chemical properties. Atoms of different elements differ in mass, size and chemical properties. Chemical combination between two elements consists in the joining together of atoms of these elements to form molecules of compounds. Drawbacks of Dalton's Atomic Theory It is now known that some of the statements of Dalton's Atomic Theory of matter are not exactly corre...

Operator Overloading // In Hindi or English // C++TUTORIAL

  Operator Overloading आज हम जानेंगे Operator overloading क्या होता है:― Operator Overloading — Operator हमेशा program के datatype के साथ काम करता है। जैसे int, float, char लेकिन जब हम अपना datatype अलग से बनाते हैं, तो इसे ही हम Operator Overloading कहते हैं।       ये user define data type पे काम करता है।अथवा ये हमारे basic data type पे work करता है। In English― T he way operators work for user-defined types like objects and structures. This is known as operator overloading. For example, Suppose we have created three objects c1 , c2 and result from a class named Complex. अगर आपको ये post अच्छी लगी हो तो हमे comment कर के जरूर बताएं।
