Run a command using arguments that come from an array

Suppose I have a graphical program named app. Usage example: app -t 'first tab' -t 'second tab' opens two 'tabs' in that program. The question is: how can I execute the command (i.e. app) from within a bash script if the number of arguments can vary? Consider this: #!/bin/bash tabs=( 'first tab' 'second tab' ) # Open the app (starting with some tabs). app  # ... How to get app -t 'first tab' -t 'second tab'? I would like the above script to have an effect equivalent to app -t 'first tab' -t 'second tab'. How can such a bash script be written? Edit: note that the question is asking about composing command line arguments on the fly using an array of arguments.
