C, C++, PHP & Java: Complete Guide to Modern Programming

Compare C's procedural programming with C++'s multi-paradigm approach, highlighting encapsulation, data hiding, and classes, while noting C++ adds inheritance, polymorphism, function overloading, and a richer standard library.

Master class definition and object creation in C++ by defining a car class with public brand, model, and year, and a display info method to print details.

Explore function overloading in c++, defining multiple functions with the same name but different parameter lists. See overloads for adding two or three integers and multiplying integers and doubles.

Explore function templates in C++ to write a single max function and multi-type templates that add mixed data types, demonstrating flexible, reusable generic programming.

Discover how streams enable text handling in C++ and compare C-style strings with the string class. Learn to concatenate strings, print results with cout, and determine string length.

Set up a PHP development environment by installing a cross-platform package, configuring Apache and MySQL, and testing a local PHP file on localhost using Sublime Text editor.

Explore the basics of PHP syntax and structure, including opening and closing tags and echo statements. Use meaningful variable names, indentation, and comments to write readable PHP code.

Learn how to declare and use PHP variables, work with strings, integers, booleans, and arrays, and perform arithmetic, assignment, and comparison operations, plus the ternary operator, with echo outputs.

Explore control flow in PHP, using if-else, switch, and loops to conditionally execute code, handle multiple cases, and repeat tasks with for and while loops.

Discover how PHP functions organize and reuse code by defining simple and parameterized functions, calling them to run tasks, and returning values like the sum of two numbers.

Learn to create arrays in PHP using the array function or shorthand syntax, access elements by index, and add, remove, or modify items while preserving keys.

Learn string functions and operations in php, including concatenation with the dot operator to build a full name. Demonstrate using length and uppercase conversions to analyze and transform strings.

Create and process HTML forms using PHP by building a simple name and email form, posting to main.php, and sanitizing input to prevent XSS.

Learn to process form data in PHP by building an HTML form, handling submissions with POST, and displaying a greeting while preventing XSS by converting characters to HTML entities.

Open, read, write, and close files in PHP, using read mode, write mode, and append mode to manage content and ensure proper file handling.

Explore classes and objects in the php tutorial series, defining a class blueprint with properties and methods, then implement inheritance with a base animal class and a dog subclass.

Explore polymorphism in PHP by treating shapes as a shape and overriding draw in circle and square; study encapsulation with a bank account's private balance and deposit and withdraw methods.

Explore PHP magic constants, automatically defined and delimited by double underscores, to access current file, line number, directory, and function or method names for debugging and maintainable code.

Set up the Java development environment by installing the Java Development Kit and an integrated development environment, configure system variables, create a Java project, and run a hello Java program.

Learn the essential syntax and structure of java, including the basic program, class and main method as the entry point, and declare int, double, and string variables.

Explore variables and data types in Java by declaring and initializing int, double, boolean, char, and string, then print results using system.out.println. Apply arithmetic operators to compute and display values.

Explore Java control flow fundamentals by implementing if-else statements, switch cases, and loops (for, while, do-while). The lecture shows practical examples and output to reinforce conditionals and iteration.

Explore how to define and call methods in Java, including parameters and return values, using a main method to produce reusable code.

Learn to define Java classes and objects, use inheritance with a base animal and a dog subclass, and implement a display method to show car and pet details.

Explore polymorphism and encapsulation in Java, showing how method overriding lets dog and cat provide their own sounds while encapsulation hides data with private fields and public methods.

Explore abstraction in Java using abstract classes and the draw and display methods, then illustrate interfaces with an animal example to implement sound and eat behaviors for scalable, modular applications.

Explore array declaration, initialization, and element access in Java, including iterating with for loops, printing values, and modifying specific indices.

Explore string manipulation in Java, including concatenation, slicing with substring, case conversion to uppercase and lowercase, printing results, and practical examples.

Explore how to use try-catch blocks in Java to handle exceptions such as arithmetic errors and division by zero, and utilize a finally block to guarantee code execution.

Explore lists, sets, and maps in Java with array lists, hash sets, and hash maps. Learn how to store, deduplicate, and access data efficiently.

Explore file handling in Java, writing to and reading from files with FileWriter, FileReader, and BufferedReader, and master console input/output using Scanner and System.in/out.

Master Java bitwise operators—and, or, not, left and right shifts, and xor—and how they operate on bits, with examples (five and three) illustrating their use in performance, encryption, and compression.
