Passing arrays in functions

football52 (176)
I'm trying to pass all the values stored in the array to another function. I'm fairly new to using arrays with functions so first of all I'm not sure if im doing it right but heres what I'm trying to accomplish.

Get the daily sales of a store for a whole year from a text file and store them in an array. Then I'm using that array throughout different functions to process the data and output it. It's not close to being done so dont nit pick it quick yet but I'm just having problems passing the values.

This is the error I get:

Error	1	error LNK2019: unresolved external symbol "double __cdecl dataProcessing(void)" (?dataProcessing@@YANXZ) referenced in function _main	C:\Users\Cody\Documents\School\C++\CIS276\DailySales\DailySales.obj	DailySales

Error	2	error LNK1120: 1 unresolved externals	C:\Users\Cody\Documents\School\C++\CIS276\DailySales\Debug\DailySales.exe	DailySales



And here is my code
