C++ Brain Teasers: Exercise Your Mind

#include <future>
#include <iostream>

int main()
{
    char counter = 0;

    auto future1 = std::async(std::launch::async, [&]()
    {
        counter++;
    });

    auto future2 = std::async(std::launch::async, [&]()
    {
        return counter;
    });

    future1.wait();
    
    // Cast to int to print it as a numerical value rather than a character
    std::cout << (int)future2.get();
}

Execute the code to understand the output and gain insights into data races and the importance of thread-safe operations.
