community variable)(2) a.ch (reference to the character member in the Community variable CH)(3) A.F (reference to double type member D in a community variable)It is not possible to refer to a community variable, such as coutTwo. Enum type1. Simply enumerate the variables, and the values of the variables can only be within the range of the values enumerated.Declares that an enumeration type begins with an enum, for example:Enum Weekday{sun,mon,tue,wed,thu,fri,sat};The elements in parentheses are

the subsequent enumeration member is added 1 on the previous member. The value of an enumeration member can be set artificially to customize an integer within a range. The enum type is an alternative to the pre-processing directive # define. The type definition is semicolon-terminated; Note: An enumeration type with the same name cannot be defined in the same program, and a named constant with the same name cannot exist in a different enumeration type.Since an enumeration is al

. In addition to giving control of the work week to your hands, Mylyn helps you better integrate team practices by simplifying the use of shared repository attributes, such as milestones and priorities, to perform all operations in Eclipse.Scheduled date and expiration dateMylyn provides two dates for scheduling: scheduled date (scheduled date) and expiration date (due, date). (You may have noticed that both dates are displayed in the Task Editor.) The scheduled date can help manage and prioriti
