JavaScript For Web Designing

JavaScript is a lightweight, cross-platform, single-threaded, interpreted compiled programming language. Also known as a website scripting language. It is known for developing web pages and is used in many environments other than browsers.

JavaScript is a weakly typed (dynamically typed) language. JavaScript, which has become an important part of Web development, is a powerful and flexible programming language. JavaScript is both an imperative and a declarative language.

JavaScript includes a standard library of objects such as arrays, dates, and mathematics, and a core set of language elements such as operators, control structures, and statements.

Client side: Provides objects that control the browser and its Document Object Model (DOM).

For example, client-side extensions allow applications to place elements on HTML forms and respond to user events such as mouse clicks, form entries, and page navigation.

Libraries that are useful on the client side include AngularJS, ReactJS, VueJS, and more. Server side: Provides objects related to running JavaScript on the server. This is because server-side extensions allow an application to communicate with a database to ensure continuity of information from one call to the application to another, or to perform file operations on the server.

Types of Polymorphism in C++

Polymorphism in C++ is a powerful concept that allows objects to be treated as instances of their parent class as well as an instance of their child classes. Polymorphism is derived from the Greek words "poly" which means many and "morph" which means forms. In C++ programming, there are mainly two types of polymorphism: compile-time polymorphism and runtime polymorphism.

Compile-time polymorphism, also known as static polymorphism or early binding, is achieved using function overloading and operator overloading. Function overloading allows different functions to have the same name but different parameters. This means that the compiler can decide which function to call based on the parameters passed to it.

For example, in C++, we can have multiple functions with the same name but different parameters like:

c

int add(int a, int b);

float add(float a, float b);

Similarly, operator overloading allows us to define the behavior of operators for user-defined data types. For example, we can overload the '+' operator for a custom class to perform addition based on our requirements.

Compile-time polymorphism provides performance benefits as the function calls are resolved at compile time.

On the other hand, runtime polymorphism, also known as dynamic polymorphism or late binding, is achieved using inheritance and virtual functions. Inheritance allows a class to inherit properties and behaviors from another class. By using inheritance, we can create a parent class and multiple child classes, each with its own unique behavior.

Virtual functions are functions in the base class that are overridden by the derived class. They allow the function to be resolved at runtime, based on the actual object being referred to. This means that the correct function is called based on the type of object at runtime. The use of the virtual keyword in C++ indicates that the function is virtual and will be resolved dynamically.

class Shape

{

public:

virtual void draw()

{

cout << "Drawing shape" << endl;

}

};

class Circle : public Shape {

public:

void draw() override

{

cout << "Drawing circle" << endl;

}

};

class Square : public Shape

{

public:

void draw() override

{

cout << "Drawing square" << endl;

}

};

In the above example, the draw() function is declared as virtual in the base class Shape and overridden in the derived classes Circle and Square. When we call the draw() function on objects of type Shape, the actual function called will depend on the type of object.

Overview of Data Structures

Data structures are a fundamental part of computer science and are essential to many aspects of programming and software development. Data structures are a way to organize and store data in a computer so that it can be accessed and modified efficiently.

There are many different types of data structures, and each has its own strengths and weaknesses. Some of the most common data structures include arrays, linked lists, stacks, queues, trees, and graphs.

Arrays are one of the basic and fundamental data structures.

They are a collection of elements, each of which is identified by an index. Arrays are used to store data of the same type in a contiguous memory space, which allows for efficient access and manipulation of the data.

Linked lists are another type of data structure that is commonly used in programming. It allows efficient insertion and removal of elements and list.

Linked lists are often used in situations where the size of the data set is not known in advance, as they can grow and shrink dynamically.

Stacks and queues are data structures that are used to store and retrieve data in a specific order. The stack is a last-in, first-out (LIFO) data structure, meaning that the last element added to the stack is the first to be removed

Queues, on the other hand, are a first in, first out (FIFO) data structure, meaning that the first element added to the queue is the first one to be removed. Queues are often used in situations where data needs to be processed in the order it was received, such as in networking or job scheduling.

Trees are a hierarchical data structure that is used to store and manage data in a way that allows for efficient searching and retrieval. Trees have a root node, which is the top of the hierarchy, and can have any number of child nodes, each of which can have its own child nodes.

Graphs are another type of data structure used to represent relationships between objects. A graph is a collection of nodes, each of which contains a reference to other nodes in the graph. Graphs are often used in situations where complex relationships need to be represented and analyzed.

Types of Variable in C++

When we write a program in C++, we often need to use variables to store and manipulate data. A variable in C++ is a named location in computer memory that holds a value. There are different types of variables in C++, each with its purpose and rules for usage. In this essay, we will discuss the different types of variables in C++ and their characteristics.

The most common types of variables in C++ are integer, float, char, and double. An integer variable is used to store whole numbers, such as 1, 2, 3, etc. In C++, an integer variable can be declared using the "int" keyword followed by the variable name. Integers can be of different sizes, such as "short int", "long int", or "unsigned int", depending on the range of values they need to represent.

Float and double variables are used to store decimal numbers, such as 1.23, 3.14, etc. In C++, a float variable can be declared using the "float" keyword, while a double variable can be declared using the "double" keyword. For example, "float x;" declares a float variable named "x", and "double y;" declares a double variable named "y".

Char variables are used to store single characters, such as 'A', 'B', 'C', etc. In C++, a char variable can be declared using the "char" keyword followed by the variable name. Char variables can also be used to represent integer values using their ASCII codes.

C++ also supports other types of variables, such as arrays, pointers, and structures. An array is a collection of variables of the same type, while a pointer is a variable that stores the memory address of another variable. A structure is a collection of variables in different types which are grouped together under one name.

C++ provides a variety of types of variables to accommodate different types of data. Each type of variable has its characteristics and uses, and understanding them is important for writing efficient and effective C++ programs.
