Can you explain the async and await features introduced in C++14?
Sure! C++14 introduced the std::async function, which allows you to run tasks asynchronously. It helps in executing functions in a separate thread.
How does std::async differ from traditional threading?
Unlike traditional threading, std::async abstracts away the thread management, making it easier to run tasks without manually handling threads.
What are the benefits of using async and await?
The main benefits include improved code readability, easier error handling, and better resource management, as it allows for non-blocking operations.
Can you give me a simple code example using async?
Certainly! Here's a simple example:
#include <future>
#include <iostream>
int main() {
auto future = std::async(std::launch::async, []() { return 42; });
std::cout << "Result: " << future.get() << std::endl;
}
