JAVA基础代码分享--学生成绩管理
问题描述:
从键盘读入学生成绩,找出最高分,并输出学生成绩等级。
成绩>=最高分-10 等级为’A’ 成绩>=最高分-20 等级为’B’
成绩>=最高分-30 等级为’C’ 其余等级为’D’
提示:先读入学生人数,根据人数创建int数组,存放学生成绩。
请输入学生人数:5
请输入5个成绩
56
74
89
41
89
最高分是:89
student 0 score is 56 grade is D
student 1 score is 74 grade is B
student 2 score is 89 grade is A
student 3 score is 41 grade is D
student 4 score is 89 grade is A
