The preceding code defines a *positional record*. The `DailyTemperature` record is a `readonly record struct`, because you don't intend to inherit from it, and it should be immutable. The `HighTemp` and `LowTemp` properties are *init only properties*, meaning they can be set in the constructor or using a property initializer. If you wanted the positional parameters to be read-write, you declare a `record struct` instead of a `readonly record struct`. The `DailyTemperature` type also has a *primary constructor* that has two parameters that match the two properties. You use the primary constructor to initialize a `DailyTemperature` record:

The `DailyTemperature` type also has a *primary constructor* that has two parameters that match the two properties. You use the primary constructor to initialize a `DailyTemperature` record. The following code creates and initializes several `DailyTemperature` records. The first uses named parameters to clarify the `HighTemp` and `LowTemp`. The remaining initializers use positional parameters to initialize the `HighTemp` and `LowTemp`:
