problems with switch case using arrays an functions

valmaral (8)
Hello everyone I'm fairly new to programming an am working on an assignment where I'm using a menu using a switch statement with arrays and functions. I'm gradually inputting the code and trying to run each function but keep getting an error saying "undefined reference to ..." . I've tried to look on the site but like I said I'm very new and I barely understand what's going on. I appreciate any help. Thanks

Hi,

did you really add all functions that you want to call ??

If i didn't miss it, you have a prototype for "printAllPaychecks" but no function with this name ...
and the compiler won't tolerate that. Even if you don't really want to enter Menu-point ... the function is nessecary to compile because you link it statically.

yeah I was adding each one by one and running them each to make sure they run correctly, but perhaps I need to add them all first. will do so then edit my message.
