For a great god-CodePudding

Student information including name, age, 3 classes (English), to achieve the following operations (100)

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

1, data entry;

2, print the highest total score students;

3, print only branch high student subjects (input);

4, print only branch fail students and the number of subjects (input);

5, according to the average descending output;

6, according to the scale (average) information query and print the students

0, quit
