Don't use static variables in header files. As headers are “incorporated” in compilation units, all variables declared as static in your header become scoped inside your compilation unit only. You won't be able to use the same global variable in your cpp files.
What did you mean by "trying to include function. Cpp in main. Cpp"?
Are you trying to use the function. Cpp's functions in main. Cpp?
In that case all you need to do is to include function. H in your main. Cpp file.
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.
