Web Programming: HTML, DHTML, XML, Scripting, Java, Servlets, Applets

 Web programming encompasses various technologies and concepts used to develop web applications. Let's explore each of them in detail: 1. HTML (Hypertext Markup Language): HTML is the standard markup language used to create the structure and content of web pages. It uses tags to define elements like headings, paragraphs, images, links, forms, etc. Example: ```html <!DOCTYPE html> <html> <head>     <title>My Web Page</title> </head> <body>     <h1>Hello, World!</h1>     <p>This is a paragraph.</p>     <img src="image.jpg" alt="Image">     <a href="https://www.example.com">Visit Example</a> </body> </html> ``` 2. DHTML (Dynamic HTML): DHTML is a combination of HTML, CSS, and JavaScript that allows web pages to become more dynamic and interactive. Example (DHTML with JavaScript): ```html <!DOCTYPE html> <htm...

Programming in C++: Tokens, Identifiers, Variables and Constants; Data types, Operators, Control statements, Functions Parameter Passing, Virtual Functions, Class and Objects; Constructors and Destructors; Overloading, Inheritance, Templates, Exception and Event Handling; Streams and Files; Multifile Programs.

 Let's cover each topic related to programming in C++ in detail: 1. Tokens, Identifiers, Variables, and Constants: These concepts in C++ are similar to those in C. Tokens are the smallest individual units, identifiers are used to name variables, functions, etc., variables store data, and constants are fixed values. Example: ```cpp #include <iostream> int main() {     int num = 42;  // 'int', 'main', 'return', '42', '=', ';' are tokens     std::cout << "Value of num: " << num << std::endl;     const float PI = 3.14;  // 'const', 'float', 'PI', '=', '3.14', ';' are tokens     return 0; } ``` 2. Data Types: C++ supports various data types such as int, float, char, bool, etc., and allows the creation of user-defined data types using classes. Example: ```cpp #include <iostream> int main() {     int age = 30;  // 'int' is a data type     float pi...

Object Oriented Programming: Class, Object, Instantiation, Inheritance, Encapsulation, Abstract Class, Polymorphism

 Object Oriented Programming: Class, Object, Instantiation, Inheritance, Encapsulation, Abstract Class, Polymorphism Object-Oriented Programming (OOP) is a programming paradigm that focuses on organizing code into objects, which are instances of classes. OOP encourages the use of concepts such as inheritance, encapsulation, and polymorphism to create reusable and maintainable code. Let's explore each of these concepts in detail: 1. Class: A class is a blueprint or template for creating objects. It defines the attributes (data members) and behaviors (member functions) that the objects of the class will have. Classes act as user-defined data types that encapsulate data and methods related to a specific entity or concept. Example: ```java class Person {     String name;     int age;     void introduce() {         System.out.println("Hi, I am " + name + " and I am " + age + " years old.");   ...

Tokens, Identifiers, Data Types, Sequence Control, Subprogram Control, Arrays, Structures, Union, String, Pointers, Functions, File Handling, Command Line Argumaents, Preprocessors in C with example

 Let's discuss each concept briefly and provide examples for better understanding: 1. Tokens: Tokens are the smallest building blocks in C programming. They include keywords, identifiers, constants, strings, operators, and punctuators. Example: ```c #include <stdio.h> int main() {     int num = 42;  // 'int', 'main', 'return', '42', '=', ';' are tokens     printf("Hello, World!");  // 'printf', '(', ')', 'Hello, World!', ';', are tokens     return 0;  // 'return', '0', ';' are tokens } ``` 2. Identifiers: Identifiers are names used to identify variables, functions, or other user-defined entities. Example: ```c int age = 30;  // 'age' is an identifier (variable name) void displayMessage() {  // 'displayMessage' is an identifier (function name)     // function body } ``` 3. Data Types: Data types define the type of data that can be stored in ...

Tokens in C with example

 In C programming, a token is the smallest individual unit in the source code that the compiler can understand. Tokens are building blocks of C programs and are used to form expressions, statements, and other elements in the code. C tokens are of various types, such as keywords, identifiers, constants, strings, operators, and punctuators. Let's explore each type of token with examples: 1. Keywords: Keywords are reserved words in the C language that have a specific meaning and cannot be used as variable names. Examples of C keywords include `int`, `float`, `if`, `else`, `for`, `while`, etc. ```c #include <stdio.h> int main() {     int num = 10;  // 'int', 'main', 'return' are keywords     if (num > 0) {         printf("Positive number\n");  // 'if', 'printf' are keywords     }     return 0;  // 'return' is a keyword } ``` 2. Identifiers: Identifiers are names used t...

Python GUI

 Learning Python GUI programming involves using libraries like Tkinter, PyQt, or wxPython to create graphical user interfaces for your applications. In this step-by-step guide, we'll use Tkinter as it comes with Python by default and is easy to get started with: Tkinter is a powerful GUI library in Python with a wide range of widgets and functionalities. Here's an overview of some common options and widgets in Tkinter, along with examples: 1. Basic Window Creation: ```python import tkinter as tk root = tk.Tk() root.title("My Window") root.geometry("400x300") root.mainloop() ``` 2. Labels: ```python import tkinter as tk root = tk.Tk() label1 = tk.Label(root, text="Hello, Tkinter!") label1.pack() label2 = tk.Label(root, text="This is a label with a background color.", bg="yellow") label2.pack() root.mainloop() ``` 3. Buttons: ```python import tkinter as tk def on_button_click():     label.config(text="Button clicked!") r...
