(十八) 结构体(国外英语资料) (eighteen) structure.Txt A structure is a combination of various variables that are made up of the basic data type and named with an identifier. Different data types can be used in the structure. Definition of structure and definition of structural variable In Turbo C, the structure is also a data type, and you can use structure variables, so, like other types of variables, you define the structure variable when you use it. The general format for defining structural variables is: Struct structure name { Type variable name; Type variable name; ... } structure variables; The structure name is the identifier of the structure, not the variable name.

If the variable name person is omitted, it becomes a description of the structure. Structural variables can also be defined with the name of an already specified structure. This definition above into: Struct string { Char name[8]; Int age; Char sex[4]; Char depart[20]; Float, wage1, wage2, wage3; }; Struct string person; If you need to define multiple structured variables with the same form, it is convenient to use this method. First, the structure is illustrated, and then the structure name is used to define the variables. Such as: Struct, string, Tianyr, Liuqi,...; If the name of the structure is omitted, it is called an anonymous structure, which is often present within the function, and the previous example of this structu
