That condition, not knowing... is usually solved by reading... Not by asking for help that is obvious if you had taken the trouble to find some examples, read them and then do the rest of the work.. read some more until you do understand it...
Pain is the final teacher... If you wish to not experience the pain then you must do the work "Yourself"... once you have done all the research... and read a book or two... then when you get stuck at "See Bobby Run" you just might find that you've already found the answer... Ya Think?
BTW I bought my first Uno in 2012 and I've posted 3 questions here since then... I also managed to read 3 C/C++ books in the same time.
Look at my post count...
