Hi,  
I need to create a lot of variables with the same name, but with different numbers after the name, like that(obviously doesn’t work):

```auto
void setup(){
  for(int i = 10;i>=0;i--){
    int "var" + char(i);
  }
}

```

What can i use to accomplish this task?

just not do it!  
how about using a array or a array list to keep that data?

I actually forgot that there are such things as arrays, thanks!
