What is the equivalent of dictionary structure Of key Value pairs?

I am not sure what you mean by this question. The structure that takes a key to a value is a map. There are many kinds of maps. The particular kind of map depends upon whether there is an array or a linked list or some other database, whether concurrent reads and writes are permitted, how efficient…

Ok how can i store 10 sets of temp, humidity values, like: dataArray = { {t1,h1}, {t2,h2}, {t3,h3} }; I've got this so far: int smsSampleCount=0; void MainAlarm(){ Serial.println("Main Alarm..."); double temp = 59.0 + smsSampleCount; double hum = 99.0 + smsSampleCount; //Store data …

Perhaps it is time to learn about C/C++ struct. There may also be an array of struct. Interesting code, but without knowing its purpose and the definition of its functions, it is meaningless to me.

Since it looks like you want to group Temp/Humidity pairs, I'd go with an array of structures.

Marciokoko: What is the equivalent of dictionary structure Of key Value pairs? If you mean something equivalent to a Python dictionary or a Ruby hash then my feeling is that it would be difficult to implement in the small memory of an Arduino. As others have said, a struct is probably the way t…

It seems that you are proposing a two dimensional array. That could work. You allocate the array and you choose where in the array data is stored.

Marciokoko: How do I make sure they are ordered in the order they were sampled? That is an interesting question in the context of the Thread title because the one thing that is NOT known with a Python dictionary (or a Ruby hash) is the order in which the items are stored. However with an array …

Well originally I thought of a dictionary because I was thinking of a dictionary of arrays: { timestamp= [T,H], timestamp = [T,H], timestamp = [T,H] } I should've expressed my idea more clearly. So I should just store each item in the array using the index. What Im confused about is the following. …

Yes, that is confusing. Why not a single 2-D array?

So what about storing them like:

dataArray= { {T1,H1}, {T2,H2}, ...};

How do I make sure they are ordered in the order they were sampled?
