Truly understanding the difference between procedural and functional?

The real difference between functional and imperative programming is the mindset - imperative programmers are thinking of variables and blocks of memory, whereas functional programmers are thinking, "How can I transform my input data into my output data" - your "program" is the pipeline and set of transforms on the data to take it from the Input to the Output. That's the interesting part IMO, not the "Thou shalt not use variables" bit.

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.
