Answer 1

because if you removed -private: string name-, you'll use a variable *name* that not declared in the class in the setter

Answer 2

So where can I declare the *name* variable I tried changing the code many times but couldn't

Answer 3

why do you want to remove it
it is declared as you do in your code
