Compared with static, const is not a storage course. It's properly a flag to the compiler telling it, "This identifier can only be initialized to a price, and never transformed again."
Everytime you are defining a const field its price must be assigned at enough time of declaration itself, after that we are not able to change its value. Undergo the next instance to know it
