Program crashes when using a class' member function, but not when implementing that function directly in main()?

It may not look obvious to you, but this is a recursive call. It keeps calling itself, without a terminal condition. Eventually, you fill up the stack by infinitely calling this function.

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.
