It s programmer preference   Personally  I love using this since it explicitly marks the object members   Of course the   does the same thing  only when you follow the convention

For the example case above  it is usually omitted  yes   However  either way is syntactically correct

Yes  it is not required and is usually omitted  It might be required for accessing variables after they have been overridden in the scope though   Person  Person         int age      this- gt age   1      Also  this   Person  Person int  age        age    age      It is pretty bad style  if you need an initializer with the same name use this notation   Person  Person int age    age age       More info here  https   en cppreference com w cpp language initializer list

this points to the object in whose member function it is reffered  so it is optional

Either way works  but many places have coding standards in place that will guide the developer one way or the other   If such a policy is not in place  just follow your heart   One thing  though  it REALLY helps the readability of the code if you do use it  especially if you are not following a naming convention on class-level variable names
