Should I use “#pragma GCC …” or “#pragma clang …” in Xcode?

Generally, you should prefer pragma GCC in cases where the pragma is GCC-specific, or is equally applicable to GCC, Clang, and other compilers which try to be GCC-compatible (such as ICC). Use pragma clang in cases where the pragma is in some way Clang-specific (such as a diagnostic option which doesn't exist in GCC).

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.
