3. Design a "student" category
1> Property
* Name
* Birthday
* Age
* Height (unit is m)
* Weight (unit is kg)
* Gender
* C language Score
* OC Results
* iOS Score
2> behavior
* Running: Every run, height increased by 1cm, weight loss 0.5kg, output after running the weight
* Eat: Every time, height increases 1cm, weight gain 0.5kg, output after eating the weight
* Study: Each study once, 3 can score each plus 1 points, output after the study of 3 subjects results
* Sleep: Output all the properties
* Compare C language scores: Compare C language scores with another student, return to poor grades (own score-other people's scores)
* Compare OC Scores: Compare OC language scores with another student, return to poor grades (own score-other people's scores)
* Compare iOS scores: Compare iOS with another student, return to poor grades (your score-other people's scores)
* Calculate total Score: Figure out the total score of 3 subjects
* Calculate average score: Calculate the average score of 3 subjects
