Concept explainers

Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Question

a. Python does not directly enforce
public and private member access
and so will not generate an error if
you fail to respect the convention.
O b. Python supports the concept of
public and private through
convention - by adding an
underscore '_' at the beginning of
the member function or variable.
C.
Just like other languages that
support Object Oriented
Programming, such as C++ and Java,
Python strictly enforces the concept
of public and private class members
and will generate an error when it
runs if you try to access a private
member from outside of the class.
O d. Python does not support the
concepts of public and private
members of a class.

Language is C++ Lab14A: The Architect. Buildings can be built in many ways. Usually, the architect of the building draws up maps and schematics of a building specifying the building’s characteristics such as how tall it is, how many stories it has etc. Then the actual building itself is built based on the schematics (also known as blueprints). Now it is safe to assume that the actual building is based off the blueprint but is not the blueprint itself and vice versa. The idea of a classes and objects follows a similar ideology. The class file can be considered the blueprint and the object is the building following the analogy mentioned above. The class file contains the details of the object i.e., the object’s attributes (variables) and behavior (methods). Please keep in mind that a class is a template of an eventual object. Although the class has variables, these variables lack an assigned value since each object will have a unique value for that variable. Think of a form that you…

Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }
