Comment

// Custom class to perform some action in the destructor when the object goes out of scope
class DoAction
    {
public:
    DoAction (std::function<void ()> func) : m_func (func)
        {
        }
    ~DoAction ()
        {
        m_func ();
        }

private:
    std::function<void ()> m_func;
    };

// Then, create an object of the class in the following way
DoAction action([&] {/*Code that you want to be executed upon leaving the scope.*/});
