There were several issues on your code, but the most important point is that memmove() does not copy the null character byte of the string.
Buffer8 is a char, %s waits for string, meaning char *, pass &buffer8 instead. You get segmentation fault because printf tries to treat a char as a pointer to char, which is address (and if a char is passed it's unlikely to be a valid one).
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.
