offset of i:0x10 This time there was no previous optimization. Can infer: g++ if the parent class is also a derived class when the parent class is guaranteed to be intact, the parent class will only guarantee the intact integrity of the fragment .That is, in the first code example, the intact integrity of the Father class in the son class is done by guaranteeing the Grandpa class's intact rows and the integrity of the data unique to the Father class char a2 . So though the size of
