在实际问题中，一组数据往往具有不同的数据类型。例如， 在学生登记表中，姓名应为字符型；学号可为整型或字符型； 年龄应为整型；性别应为字符型；成绩可为整型或实型。 显然不能用一个数组来存放这一组数据。 因为数组中各元素的类型和长度都必须一致，以便于编译系统处理。为了解决这个问题，Ｃ语言中给出了另一种构造数据类型——“结构”。 它相当于其它高级语言中的记录。-In the actual problem, a set of data tend to have different data types. For example, in the student registration form, name should be character　Student id for integer type or character　Age should be integer　Sex should be character　For integer or real. Obviously can t use an array to store a set of data. Because of the type and length of each element in the array must be consistent, so that the compiler system processes. In order to solve this problem, C language is given another structure data type,　structure . It is equal to the record of other high-level languages.
