Readonly and other things about C++

1. in c#

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;

}

I am sure none will try to change it in the methods. The same for static. Only one way I will use static:

when I need to use a static method. That is all. Please forget the differece of static readonly and const.

We don't need it totally.

 

When I interviewed with Microsoft one year ago.

I am aware of that, the most important things of c# are all in Effective C#.

If you understand all items, you understand how to use c#.
