- Today, we’re delving into Inheritance. Check out the attached tutorial for learning materials and an instructional video!
You are given two classes, Person and Student, where Person is the base class and Student is the derived class. Completed code for Person and a declaration for Student are provided for you in the editor. Observe that Student inherits all the properties of Person.
Complete the Student class by writing the following:
A Student class constructor, which has parameters:
- A string, first name.
- A string, last name.
- An integer, id.
- An integer array (or vector) of test scores, scores.
- A char calculate() method that calculates a Student object’s average and returns the grade character representative of their calculated average:
- Grading Scale
- O : 90 <= a <= 100
- E : 80 <= a < 90
- A : 70 <= a < 80
- P : 55 <= a < 70
- D : 40 <= a < 55
- T : a < 40
- Grading Scale
- Input Format
- The locked stub code in your editor calls your Student class constructor and passes it the necessary arguments. It also calls the calculate method (which takes no arguments).
- You are not responsible for reading the following input from stdin: The first line contains first name, last name, and id, respectively. The second line contains the number of test scores. The third line of space-separated integers describes scores.
1 <= first name , last name <= 10 id = 7
- 0 <= score, average <= 100
- Output Format
- This is handled by the locked stub code in your editor. Your output will be correct if your Student class constructor and calculate() method are properly implemented.
- 설명은 긴데.. 그냥 Person 클래스를 상속받고, 생성자 함수에서는 score를 추가하여 준다
- score를 평균을 낸 뒤에, 해당 평균이 어느 구간에 속하면 O, E, A, P, T, D를 리턴하게 만들어주면 됨
