Can you explain line by line what the below C++ program is doing. Please and thank you C++ source code: #include <iostream>#include <thread>#include <atomic> std::atomic<int> counter(0); void incrementCounter(int iterations) { for (int i = 0; i < iterations; ++i) { counter.fetch_add(1, std::memory_order_relaxed); // std::memory_order_relaxed is used for simplicity, you may choose a different memory order based on your requirements }} int main() { const int numThreads = 5; const int iterationsPerThread = 100000; std::thread threads[numThreads]; // Launch threads for (int i = 0; i < numThreads; ++i) { threads[i] = std::thread(incrementCounter, iterationsPerThread); } // Join threads for (int i = 0; i < numThreads; ++i) { threads[i].join(); } std::cout << "Counter value: " << counter.load(std::memory_order_relaxed) << std::endl; return 0;}
