Program Code – In C++: Exploring Advanced Features and Concepts

#include <iostream>
#include <memory>
#include <vector>
#include <algorithm>
#include <tuple>

// Custom comparator for sorting with a lambda expression.
struct CustomCompare {
    bool operator()(const std::tuple<int, std::string>& a, const std::tuple<int, std::string>& b) {
        return std::get<0>(a) < std::get<0>(b); // Compare based on the integer element.
    }
};

// Function template to display elements of a container.
template<typename T>
void display_container(const T& container) {
    for (const auto& element : container) {
        std::cout << element << ' ';
    }
    std::cout << '
';
}

int main() {
    // Using smart pointers for automatic memory management.
    auto smartInt = std::make_unique<int>(42);

    // Demonstrate smart pointer usage.
    std::cout << 'Smart pointer value: ' << *smartInt << '
';

    // Demonstrate usage of vectors and sort with a lambda.
    std::vector<std::tuple<int, std::string>> vec;
    vec.emplace_back(3, 'C++17');
    vec.emplace_back(1, 'C++11');
    vec.emplace_back(4, 'C++20');
    vec.emplace_back(2, 'C++14');

    // Sorting using the custom comparator.
    std::sort(vec.begin(), vec.end(), CustomCompare());

    // Display the sorted vector.
    std::cout << 'Sorted vector: 
';
    for (const auto& [number, str] : vec) {
        std::cout << number << ':' << str << '
';
    }

    // Dynamic polymorphism via smart pointers.
    struct Base {
        virtual void speak() const { std::cout << 'Base class speaking.
'; }
        virtual ~Base() = default;
    };
    
    struct Derived : public Base {
        void speak() const override { std::cout << 'Derived class speaking.
'; }
    };

    std::unique_ptr<Base> basePtr = std::make_unique<Derived>();
    basePtr->speak();

    return 0;
}

Code Output:

Smart pointer value: 42
Sorted vector: 
1:C++11
2:C++14
3:C++17
4:C++20
Derived class speaking.

Code Explanation:

The program demonstrates some advanced C++ features and concepts, including smart pointers, lambda expressions, tuples, custom comparators, generic functions, and polymorphism.

1. Smart pointers (std::unique_ptr specifically here) handle dynamic memory allocation by ensuring automatic deletion of the pointer to prevent memory leaks. ‘smartInt’ is declared using std::make_unique which initializes it with an int value of 42.
2. std::vector and std::tuple are used to create a list of pairs (though not std::pair, but similar) of integer and string values representing versions of C++. std::tuple allows us to store a collection of potentially differently-typed values together.
3. We fill the vector using emplace_back which constructs the elements in place, improving performance by eliminating unnecessary copy operations.
4. std::sort is used to sort the vector, but instead of the default sorting, we use a custom comparator ‘CustomCompare’, which prioritizes sorting based on the integer part of our tuples.
5. We iterate over the sorted vector and print out the contents to demonstrate the effect of our sorting. We utilize structured binding (introduced in C++17) to unpack the tuple into ‘number’ and ‘str’.
6. We showcase dynamic polymorphism using smart pointers. A base class ‘Base’ and a derived class ‘Derived’ are defined, with Derived overriding the virtual ‘speak’ method.
7. We declare a smart pointer of type Base and assign it an instance of Derived. When calling the ‘speak’ method on this pointer, it correctly calls the overridden method in Derived, showing polymorphism in action.

Overall, these concepts are crucial for writing modern C++ code that is both robust and efficient. By utilizing these advanced features, programmers can write less boilerplate, achieve better performance, and reduce common coding errors like memory leaks.
