The literal meaning of polymorphism is the condition of occurrence in different forms. Polymorphism is a very important concept in programming. It refers to the use of a single type entity (method, operator or object) to represent different types in different scenarios. Let's take an example: ...
Polymorphism is a popular concept in object-oriented programming (OOP), referring to the idea that an entity in code such as a variable, function orobjectcan have more than one form. The wordpolymorphismis derived from Greek and means "having multiple forms." Apart from computer programming, t...
Polymorphism... Animal a = new Dog(); We can create new references that point to different types in the same block of memory. a Animal Dog Object a Animal Dog Object o Animal a = new Dog(); Object o = a; In some sense, casting is a type of polymorphic behavior. Dynamic Binding ...
As Haugen (1966, p. 931) points out, "The ideal case of minimal variation in form would be a hypothetical, 'pure' variety of a language having only one spelling and one pronunciation for every word, one word for every meaning, and one grammatical framework for all utterances." From this...

Until you reach the Module 08: STL, meaning no Containers (vector list map and so forth) and no Algorithms (anything that requires to include the <algorithm> header). Memory leaks when using new. Function implementations in header files (except for function templates). Allowed: Use standard ...
As the meaning is implicit, in compile time polymorphism, the flow of control is decided in compile time itself. It is achieved using method overloading. In method overloading, an object can have two or more methods with the same name, but the method parameters are different such that: ...
totaling four data members. Here again the virtual pointer is the first data member. Similarly, classZinherits from classY, meaning that classZwill first contain all the data members of classYfollowed by one of its own. So it will have a total of five data members, where the virtual pointe...
