How do I avoid exceptions and handle errors std::tuple in C++?

In C++, handling errors without using exceptions can be done through various means, particularly when dealing with data structures like `std::tuple`. Instead of relying on exceptions, you can use error codes, `std::optional`, or a custom error handling approach to manage potential issues gracefully.

Here’s an example demonstrating how to handle errors when working with `std::tuple` without throwing exceptions:


        #include 
        #include 
        #include 
        #include 

        std::optional<:tuple std::string>> safeGetTuple(bool succeed) {
            if (succeed) {
                return std::make_tuple(1, "Hello");
            }
            return std::nullopt; // Indicating failure
        }

        void processTuple(const std::optional<:tuple std::string>>& optTuple) {
            if (optTuple) {
                int num;
                std::string str;
                std::tie(num, str) = *optTuple; // Accessing tuple elements
                std::cout << "Number: " << num << ", String: " << str << std::endl;
            } else {
                std::cout << "Error: Tuple could not be retrieved." << std::endl;
            }
        }

        int main() {
            auto tupleResult = safeGetTuple(false); // Simulate failure
            processTuple(tupleResult);

            tupleResult = safeGetTuple(true); // Simulate success
            processTuple(tupleResult);

            return 0;
        }
