Programing In C++ is a certification course for everyone who have basic knowledge of C.
What Is C++ ?View Details
“C++ is a statically-typed, free-form, (usually) compiled, multi-paradigm, intermediate-level general-purpose middle-level programming language.” In simple terms, C++ is a sophisticated, efficient and a general-purpose programming language based on C. It was developed by Bjarne Stroustrup in 1979.
Difference Between C & C++View Details
When compared to C++, C is a subset of C++.
C supports procedural programming paradigm for code development.
C++ supports both procedural and object oriented programming paradigms; therefore C++ is also called a hybrid language.
Being an object oriented programming language C++ supports polymorphism, encapsulation, and inheritance.
In C++ (when it is used as object oriented programming language), data and functions are encapsulated together in form of an object. For creating objects class provides a blueprint of structure of the object.
In C, data are free entities and can be manipulated by outside code. This is because C does not support information hiding.
In C++, Encapsulation hides the data to ensure that data structures and operators are used as intended. etc.
Procedure-Oriented ProgramingView Details
A procedural language, as the name implies, relies on predefined and well-organized procedures, functions or sub-routines in a program’s architecture by specifying all the steps that the computer must take to reach a desired state or output.
A program in a procedural language is a list of instruction where each statement tells the computer to do something. It focuses on procedure (function) & algorithm is needed to perform the derived computation.
Object Oriented ProgramingView Details
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods.
Object-oriented programming (OOP) is a programming language model organized around objects rather than "actions" and data rather than logic. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data.
Application of OOPView Details
The concept of a data class makes it possible to define subclasses of data objects that share some or all of the main class characteristics. Called inheritance, this property of OOP forces a more thorough data analysis, reduces development time, and ensures more accurate coding.
Since a class defines only the data it needs to be concerned with, when an instance of that class (an object) is run, the code will not be able to accidentally access other program data. This characteristic of data hiding provides greater system security and avoids unintended data corruption.
The definition of a class is reuseable not only by the program for which it is initially created but also by other object-oriented programs (and, for this reason, can be more easily distributed for use in networks).
The concept of data classes allows a programmer to create any new data type that is not already defined in the language itself.
The building block of C++ that leads to Object Oriented programming is a Class. It is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. A class is like a blueprint for an object.
A class is defined in C++ using keyword class followed by the name of class. The body of class is defined inside the curly brackets and terminated by a semicolon at the end.
Web design is a process of conceptualizing, planning, and building a collection of electronic files that determine the layout, colors, text styles, structure and use of interactive features.
Digital marketing, the promotion of products or brands via one or more forms of electronic media, differs from traditional marketing in that it uses channels and methods .
Web development broadly refers to the tasks associated with developing websites for hosting via intranet or internet.
