if

#include <iostream> using namespace std; int main() { int score; cout << "请输入学生成绩（整数）："; cin >> score; if (score >= 86) { cout << "VERY GOOD" << endl; } else if (score >= 60) { cout << "GOOD" << endl; } else { cout << "BAD" << endl; } return 0; }

switch

#include <iostream> using namespace std; int main() { int score; cout << "请输入学生成绩（整数）："; cin >> score; // 分段判断，用区间整除10分类 int level = score / 10; switch(level) { case 10: // 100分 case 9: // 90~99 case 8: // 80~89，其中86及以上才是VERY GOOD if (score >= 86) cout << "VERY GOOD" << endl; else cout << "GOOD" << endl; break; case 7: case 6: // 60~79 cout << "GOOD" << endl; break; default: // 0~59 cout << "BAD" << endl; break; } return 0; }
