Program Code – Where C++ Language Is Used Nowadays: Current Trends and Domains

#include <iostream>
#include <thread>
#include <vector>
#include <mutex>
#include <algorithm>
#include <cmath>

// Define a concurrent queue with thread-safe operations
template<typename T>
class ThreadSafeQueue {
private:
    std::vector<T> elements;
    mutable std::mutex mtx;

public:
    // Pushes an item to the back of the queue
    void push(T value) {
        std::lock_guard<std::mutex> lock(mtx);
        elements.push_back(value);
    }

    // Pops an item from the front of the queue if not empty
    bool pop(T &value) {
        std::lock_guard<std::mutex> lock(mtx);
        if (elements.empty()) {
            return false;
        }
        value = elements.front();
        elements.erase(elements.begin());
        return true;
    }
};

// Function to simulate a complex calculation
double complexCalculation(double input) {
    return std::pow(input, 2.0);
}

// Example usage in a multi-threaded environment
int main() {
    // Create a queue shared by threads
    ThreadSafeQueue<double> queue;

    // Create and launch thread to perform complex calculations
    std::thread worker([&]() {
        double value;
        while (queue.pop(value)) {
            double result = complexCalculation(value);
            std::cout << 'Computed: ' << result << '
';
        }
    });

    // Main thread simulating enqueue operations
    for (double i = 0.5; i <= 10.0; i += 0.5) {
        queue.push(i);
    }

    // Wait for calculation thread to finish
    worker.join();

    return 0;
}

Code Output:

The output will be a series of computed results from the complexCalculation function, displayed on the console. Since the calculation is just raising the number to the power of two, we will see its square being printed. For example, for the input 0.5, the output would be Computed: 0.25, followed by others up to the input 10.0.

Code Explanation:

The provided code snippet demonstrates a multi-threaded application in C++ which is a common scenario in many real-world systems such as game engines, high-performance computing, and simulations. Let me unpack it step by step:

1. We’ve got a ThreadSafeQueue template class that encapsulates a standard vector and mutex, ensuring thread-safe push and pop operations. This kind of data structure is quite handy, particularly when you’ve got multiple threads needing synchronized access to shared resources.

2. There’s a function complexCalculation which is more of a placeholder here, mimicking some intensive number-crunching work, squaring its input.

3. In the main() function, the queue is spawned, and we’re kicking off a worker thread that keeps popping values from the queue and computing results using our stubbed complexCalculation.

4. The main thread, in the meantime, is busy stuffing the queue with a sequence of doubles.

5. Finally, after all the enqueuing, the main thread hangs tight until the worker has burnt through the queue and we call it a day.

What you’re seeing here is a simple pattern of a producer-consumer scenario which is a cornerstone in concurrent programming. It demonstrates the power of modern C++ to handle complex tasks with elegant and high-level abstractions, without getting your hands dirty with raw threading APIs. And let’s not forget, this is high-performance stuff – C++ doesn’t play when it comes to speed.
