As noted in other answers, this is because of the mismatch between the format string and the type of the argument.
When you say %d in the printf format string, you must pass an int value as the corresponding argument. Otherwise the behavior is undefined, meaning that your computer may crash or aliens might knock at your door. Similar for %f and double.
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.
