C++ Threads and Async

Execute multithreaded concurrent code with std::thread and std::async.

❮ Previous Next ❯

The <thread> and <future> libraries provide standardized concurrency primitives: std::thread for background tasks, and std::async to return futures.

Key Takeaways: C++ Threads and Async

Mastering C++ Threads and Async helps you write clean and reliable C++ code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

C++ Threads and Async Code Example

C++

#include <iostream>
#include <future>

int calculateSum(int a, int b) { return a + b; }

int main() {
    std::future<int> result = std::async(calculateSum, 15, 25);
    std::cout << "Async sum: " << result.get() << "\n";
    return 0;
}

Output

Async sum: 40
