14. C – Function Call
And now you want to know which programs are using this function: “Called Function” gives you the answer:

15. Ok, no problem: The function is only used in two members
C – Function Call

16. C – Files
And now you want to know which programs are using this function: “Called Function” gives you the answer:

17. These programs are writing to the console
C - Files
