Generic Stack Implementation Creating a reusable stack structure requires leveraging C++ templates. This allows the data structure to handle various types without rewriting logic for each specific type. The following implemantation defines a dynamic stack capable of storing elements of any specified type. #include <iostream> #include < ...

operator T() const operator T() const is a type conversion operator overload in C++ that enables implicit conversion from a class type to a target type T. Basic Usage When an object of a class appears in a context requiring type T, this operator is automatically invoked. For example: class CustomClass { public: operator int() const { return ...

This article presents a robust event dispatching system that supports both synchronous and asynchronous event handling. The implementation extends a synchronous-only design to enable concurrent procesing while maintaining type safety and thread safety. Core Architecture The dispatcher uses a template-based approach where each event type gets it ...

A template-based singly linked list requires careful handling of type erasure and memory management. Unlike non-template implementations, a generic approach enforces uniform data types across all nodes, including the sentinel head node. Attempting to assign a distinct type to the head node results in template instantiation conflicts and unsafe ...

Function objects, frequently termed functors, allow C++ classes to emulate callable routines by overloading the operator(). This design pattern enables object instantiation that accepts parameters and yields return values identically to standard functions, while preserving encapsulated state and type safety. Unlike conventional function pointer ...

Tmeplate parameters in C++ are not limited to types—they can also be compile-time constants, known as non-type (or numeric) template parameters. These enable powerful compile-time computations and fixed-size data structures. Constraints on Non-Type Template Parameters Must be compile-time constants—variables are not allowed. Floaitng-point val ...

Inheritance vs Composition for Data Management Consider a scenario where a class is designed to manage student grades. A common design mistake is inheriting from a standard container. Below is an implementation of VectorGradeAdapter, which inherits publicly from std::vector<int>. #include <iostream> #include <vector> #inclu ...

Number Theory Utilities Greatest Common Divisor int gcd(int a, int b) { while (b) { int temp = b; b = a % b; a = temp; } return a; } Least Common Multiple int lcm(int a, int b) { return a / gcd(a, b) * b; } Fast Exponentiation long long power(long long base, long long exp) { long long result = 1; ...

When the compiler processes a function template, it does not generate executable code immediately. Instead, it acts as a blueprint. Specific function definitions are only generated when the template is instantiated with concrete types. This process involves two distinct compilation phases: Template Definition Check: The compiler checks the tem ...

Task 1: Publisher Class Hierarchy The following code demonstrates inheritance and polymorphism using a publisher class hierarchy: main.cpp #include "publisher.hpp" #include <vector> #include <typeinfo> using std::vector; void demonstrate_polymorphism() { vector<Publisher*> media_collection; media_collection. ...
