Unexpected results when using std::function with lambda capturing variables in C++17
I've been researching this but I'm experiencing unexpected behavior when using `std::function` with a lambda that captures local variables in C++17... Here's a simplified version of my code: ```cpp #include <iostream> #include <functional> #include <vector> void executeFunction(std::function<void()> func) { func(); } int main() { std::vector<int> values = {1, 2, 3}; int multiplier = 2; for (int value : values) { auto func = [value, multiplier]() { std::cout << "Value: " << value * multiplier << std::endl; }; executeFunction(func); } multiplier = 3; // Change multiplier after lambda creation for (int value : values) { auto func = [value, multiplier]() { std::cout << "Value: " << value * multiplier << std::endl; }; executeFunction(func); } return 0; } ``` In this example, I expect the second loop to print values with the updated `multiplier`. However, I see the output as follows: ``` Value: 2 Value: 4 Value: 6 Value: 3 Value: 6 Value: 9 ``` Instead of multiplying by 3 in the second loop, it still seems to be using the original multiplier of 2 for the first two calls. I've checked that I'm not capturing `multiplier` by reference; it’s captured by value, but still, I expected the updated `multiplier` to affect the second set of outputs. I've tried using `std::bind` instead of `std::function`, but the results are the same. Can anyone explain why the first two outputs do not reflect the updated `multiplier` after the lambda captures it? What am I missing here? What's the correct way to implement this? What would be the recommended way to handle this?
