Hi I have a problem, I hope you can help me with.

I have a number, which I need to compare to some values.

I do not wish to go through all the values, and compare them individually, as I there are too many for it to be efficient.

Neither do I want to create an array with the size of the range of numbers, as it can anything from 0 UINT_MAX

So I am hoping that you might have a better solution.

Here is an example of what I have tried, but didn't work,
because I get the values dynamicly

CPP Syntax (Toggle Plain Text)

class Mother
{
public:
    Mother(){}
    ~Mother(){}
 
    template<int msg> inline void HandleMessage(){};
 
    template<> inline void HandleMessage<10>()
    {
        std::cout<<"It works!\n";
    }
};

class Mother { public: Mother(){} ~Mother(){} template<int msg> inline void HandleMessage(){}; template<> inline void HandleMessage<10>() { std::cout<<"It works!\n"; } };

Well it is an integer, compared to a list of integers.

Too time consuming. I would rather not do it at all then

And about the code snippet, if I create an instance of Mother,
and call HandleMessage<10> it would print "It works!\n".

But if I call it with any other value it would do nothing,
the reason I am not doing this, is that I don't know the values at compile time.
