Deep Dive into C++ Template Metaprogramming & Custom Data Structures

C++ offers unparalleled control over performance and system resources. Understanding template metaprogramming allows developers to write zero-cost abstractions that compile down to highly optimized machine code.

Generic Template Linked Lists & Queues

By utilizing C++ templates (template <typename T>), data structures can operate seamlessly over any data type without sacrificing performance or memory safety:

template <typename T>
class Node {
public:
    T data;
    Node* next;
    Node(T val) : data(val), next(nullptr) {}
};

template <typename T>
class LinkedList {
private:
    Node<T>* head;
public:
    LinkedList() : head(nullptr) {}
    void insert(T value);
};

Key Principles

• RAII (Resource Acquisition Is Initialization): Automatic memory management through smart pointers and custom destructors.
• Cache Locality: Structuring data layout to maximize CPU L1/L2 cache hits for high-performance algorithm execution.
