Question about c++ in unrealengine and cryengine

Hi today i have checked C++ API Reference code in cryengine then compared with C++ API Reference in unreal engine.So my question is C++ API Reference unrealengine and cryengine code are not the same ?
I don’t know if my question is confuse.I mean both are c++ but the way how they coded are not the same ?

Probably both are coded with a keyboard…
No there are different in a lot of ways
