Adressing variable using a string and an int

Well, my variables are general variables.

It doesn't matter what type of variables, global, static, automatic, whatever, their names simply do not exist at runtime.
End of story.

Quit hand-waving -
" I´d like to avoid for-loops, if possible. In my case, the code would become too complicated."
"However my original code has too many arrays. No more array please!"
" I want to have something like this:"

Tell us what you want to achieve, not how you think you ought to implement it.

I don´t understand why I shouldn´t be able to speak to the variable by contructing the name of it (e.g. sensorValue_1) !!

I don't understand why your reference can't simply be sensorValue [x]
