readonly can be delayed to initialize in constructor.
2. in c++
totally no readonly.
Many people have mastered c++ before c#. They are the managers.
So many of the interview are about the difference of c# and c++.
I am always confused about the interview problems since I never use it before.
Such as readonly. In c#, there are no pointer, we don't need const and readonly actually.
All you need to do is set a All caps up variable name as a field. such as:
class A
{
double MYPI=0.7;

We don't need it totally.
