クラスtype_infoは、型の名前も含めて、その型に関する実装固有の情報を保持し、平等または照合順序のための2つのタイプを比較することを意味します。これはtypeid子によって戻されたクラスです。.
Original:
The class type_info holds implementation-specific information about a type, including the name of the type and means to compare two types for equality or collating order. This is the class returned by the typeid operator.
