Constants #
Constant is an immutable variable.
In C#, constants are only supported for built-in types. You can’t use it for user-defined types such as classes, structs, arrays, and etc.
const int Months = 12;
const int Weeks = 52;
const int Days = 365;
Console.WriteLine($"One year is {Days} days, {Weeks} weeks, or {Months} months.");
$ dotnet run
One year is 365 days, 52 weeks, or 12 months.
