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...
