Most people associate it with an integer in. mathematics.•. Actually, int is an abstract representation of an. integer.•. ints are fixed in size (32-bits).•. if result is out of range. – “Overflow” error occurs. – "quietly" produce an incorrect result.•. Mathematical integers do not have this problem 4 Cont•. Built-in data types are only approximations or. imperfect models of real-world concepts.•. Types like int, double, char and others are all. examples of abstract data types.•. An abstract data types captures two concepts. – Data representation. – Operations that can be perform on that data.•. For example. – int contain integers values. – Operations: add, subtract, multiply, division 5 ADT in C++.•. In C++, the programmer uses classes to. implement abstract data types and their services.•. For example, to implement a array ADT. – subscript range checking. – an arbitrary range of subscripts instead of having to. start with 0. – array assignment. – array comparison. – array input/output 6 Container classes – real world.•. In real life, we use containers all the time.•. For example. – pages in your book come inside a cover or binding. – you might store any number of items in containers in. your garage.•. Without container it is inconvenient to work with. many objects. – Imagine trying to read a book that didn’t have any sort. of binding. – Eat cereal that didn’t come in a box without using a. bowl 7 Container classes – C++.•. Container classes designed to hold collections of. instance of other classes.•. Arrays, stacks, queues, trees and linked lists are. examples of container classes. 8 Two important . Separating interfaces from. . Hiding implementation from user/ achieve this by defining a class in and implementation of class function in cpp source file. 9 Proxy class.•. Proxy class allows to hide the private data. and other functions of a class from clients.•. Providing client with proxy class enables it to. use your class services with know. implementation detail of your . Interface class Client class. class. Go to. program 10 Static h class.
