Difference between const, readonly and static variables
const keyword :
A variable declared as const must be assigned a value at declaration.
And we can not change its value once it is assigned.
They are implicitly static by default.
You can apply const keyword to built-in value types (byte, short, int, long, char, float, double, decimal, bool), enum, a string literal, or a reference type which can be assigned with a value null.
readonly keyword:
The value will be initialized either at declaration time or in the constructor.
Read only values will evaluate at runtime only.
static keyword:
static variables are common to all the objects.
Each static variable is shared among all the objects of the same class.
and they do not tied to a specific object.

For static variables memory is allocated at complie time.
Memory for static variables in allocated the moment you use the class where static variable is present.
And the variable will last until program terminates.
Great

In Case of readonly field, Suppose I have two constructors first is Default constructor as shown in your example along with that I have another constructor
with parameter. Is it possible to change the value of readonly field in that second constructor ? What will happen if I will create two objects first without parameters and second with parameters .
It is possible to change the readonly variable in any constructor. It will assign the values what you are assigning. It does not matter whether the constructor is paramerised or not.
Thanks 🙏

I do not understand why sentence end with "Insallah" repetitive. You do not need to show devotions, it's between you and God. God is giving you knowledge, so embrace the knowledge. Hope you do not mind. You are doing good job.
It is initialized or initialize not "Insallah". Thank you for your comment. Please do subscribe to our channel. And share this video in facebook, whatsapp and twitter.
lolz, same here, when i listened carefully again then i understood that he saying initialize not inshallah... but very helpful video, i have searched many videos for static variable meaning, every video tells that how to use, but not tell why to use, now in this video , his video also tells y to use static variable...
'right' is not pronounced as 'rrrrright'... so annoying
Great
