输入三门功课成绩,取三门成绩平均值显示等级。(100-90为优秀,90-80为良,80-70为中,70-60为及格,<60为不及格)
#include <iostream>
using namespace std;
int main() {
double score1, score2, score3, avg;
cout << "请输入三门功课成绩:";
cin >> score1 >> score2 >> score3;
avg = (score1 + score2 + score3) / 3.0;
if (avg >= 90) {
cout << "等级:优秀" << endl;
} else if (avg >= 80) {
cout << "等级:良" << endl;
} else if (avg >= 70) {
cout << "等级:中" << endl;
} else if (avg >= 60) {
cout << "等级:及格" << endl;
} else {
cout << "等级:不及格" << endl;
}
return 0;
}
