expected primary-expression before

RotciV (11)
I am wondering why I am getting an expected primary-expression before 'remainingNumers' and expected primary-expression before 'lastNums' in line 23. Can you guys tell me what's causing this? Thanks.

Few things:

Take out the vector<int> part of line 23- you already declared it once, no need to declare it again. However, more importantly- lastNums doesn't exist. In no instance of main is it declared, yet you pass it as a parameter.

Don't I need to pass it so I can use that variable for the addNumber function?
and thanks!

You can't pass it if it doesn't exist. Either way, you don't need the variable type when passing things as a parameter in a function call- just calling addNumber(remaniningNumbers, lastNums); would work fine.

Either way, you need to create lastNums beforehand and actually fill it with what it needs to be filled with anyway. Then you can pass it.

My lastNum is in another function but I guess it doesn't exist yet since it reads the main function first.
Should I just add my lastNum function to my main function?
Ispil (788)
If it is created in another function, that means that it is local to that function- it only exists inside of it. Even though lastNums is in getEnd(), it does not exist in main, or anywhere else.
