(1 points) high-tech class highinfomation consists of seven private member variables (highnumber, highname,highcontent,highsum,highstate,highyear,highuser). (1) The meanings of the members are as follows:(4 points) The ① variable highnumber is a string that represents a high-tech information number (consisting of eight digits) and remains unique. The ② variable highname is a string of type strings, used to store high-tech information names. The ③ variable, highcontent, is a string that is used to store a high-tech information brief, no more than 20 characters. The ④ variable highsum is a double type for storing high-tech investment amounts. ⑤ variable highstate is an integer type, used for high-tech information status, 0 is not audited, 1 indicates that the demand has passed the audit, 2 means that the audit was not approved, the initial entry of high-tech information status of 0. The ⑥ variable highyear is an integral type for storing high-tech submission year information for four digits (for example: 2017 for 2017. The ⑦ variable highuser is a string type that is used to store high-tech reporting information. (2) Specific function requirements: (4 points) ① each variable defines the method of Get () (read variable information) and set () (Set variable information). ② requires defining a constructor method to assign an initial value to a variable. 4th page Total 8 page four. function requirement: 1, need to indicate class, school number, name in the note that the program starts.

I write in the test source code for your reference, no other purpose is to benefit later learning younger sister, 2017 exam content and 2016 exam content very much like, I think he this person is difficult to change, after all, a ppt for 5-6 years,---- The test questions and I wrote the source code (after the examination of the sources have not changed, but the function has been implemented, the code is not good, you can refer to the line):
