Exam registration management
The examination registration system is a simple simulation of examination registration management. You can use the menu selection method to complete the following functions: Enter the examinee information; output the examinee information; query the examinee information; Add the examinee information; modify the examinee information; delete the examinee information. Each candidate information is composed of the admission ticket number, name, gender, age, and application type.
Requirement: define a special elemtype to describe the examinee information. The data structure is described by a class and named as list, including data, relations, and basic operations; the storage structure of the data structure is implemented using a chain structure.
