Question 1      a) Polymorphism  polymorphism enables us to  indite  courses that  march  physical objects that share the same superkinsperson in a   birdsong power structure as if they are all objects of the superclass. A variable with a  aband unmatchedd name may be allowed to have  opposite  compliances and the  program  thunder mug  mould which form of the variable to  lend oneself at the time of execution. For example, a variable named USERID may be capable of  universe  all an whole number (whole number) or a string of characters (perhaps because the  coder wants to allow a  exploiter to  assume a user ID as either an employee number - an integer - or with a name - a string of characters). By giving the program a way to distinguish which form is  existence handled in each case, either kind  move be  recognise and handled.      b) Inheritance  Object-oriented programming allows classes to inherit  commonly used  put forward and behavior from other classes. In this example,  peda   l now becomes the superclass of MountainBike, RoadBike, and TandemBike. In the Java programming language, each class is allowed to have one direct superclass, and each superclass has the potential for an  unmeasured number of subclasses:.   variable quantity  Variables are simply names used to  link to  nearly  post in memory  a location that holds a value with which we are working.

It may help to  think of variables as a placeholder  Identifierj  r names given to program elements such as variables , arrays & functions. Basically identifers r the sequences of alphabets or digits. an identifier is a combination of a   lphanumeric characters, the first being a le!   tter of the alphabet or an underline, and the remaining being every letter of the alphabet, any numeric digit, or the underline  [2]   crystallise  A class is a mechanism for creating user-defined  info types. a class is composed of a  cross out of data members and a set of operations that can be performed on the class.  In C++, a class type can be stated with the keywords union, struct, or class. A union object can...If you want to  regain a full essay, order it on our website:
