题解 | 学生综合评估系统

题干解读：给出学生的两个得分，要更具所给的两个条件判断该学生是否为EXCELLENT

思路：先求出综合成绩s和总成绩sum,再根据这两个成绩来判断即可.

#include<bits/stdc++.h>
using namespace std;

// 定义学生结构体
struct Student{
    int id;
    int academic_score;
    int activity_score;
};

// 评估函数：判断学生是否优秀
bool isExcellent(Student student){
    double s,sum;
    sum = student.academic_score+student.activity_score;
    s=student.academic_score*0.7+student.activity_score*0.3;
    if(sum>140 && s>=80){
        return true;
    }
    return false; 
}

































































































































































































//主函数用于读入数据调用函数，请勿修改
int main(){
    int n;
    cin >> n;
    Student student;
    for(int i=1;i<=n;i++){
        cin >> student.id >> student.academic_score >> student.activity_score;
        if (isExcellent(student)) cout << "Excellent\n";
        else cout << "Not excellent\n";
    }
    return 0;
}
