        throw std::exception();
    return (inNumberator / inDenominator);
}

int main(int argc, char *argv[])
{
    try {
        std::cout << divideNumbers(2.5, 0.5) << std::endl;
        std::cout << divideNumbers(2.3, 0) << std::endl;
    } catch (std::exception excepiton) {
        std::cout << "An exception was caught!" << std::endl;
