[Ümit Terzi]

First of all hello everyone

I'll keep getting the same error message in the code I gave you below.

I'd appreciate it if you'd help.

Thanks

Ümit Terzi: I'll keep getting the same error message in the code I gave you below.

                              void  arList();

                              genel(void);

You said there are two functions but never provided their code.

What do you think is the solution?

Ümit Terzi: What do you think is the solution?

1. Provide their code.
2. Or, stop declaring nonexistent functions / methods / constructors.
