That's correct. It's why they're called "global" variables: they're available in any scope.
Note that your header file as written defines the global variable state (it declares an incomplete array lnArray); it should just declare them.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
