学生成绩核算系统的设计与实现(25)
要求:(1)按班级按课程从文件中读入相应的平时成绩、期中考试成绩和期末考试成绩。
(2)三个成绩对总评成绩的百分比被定义为常数,各占总成绩的30 、30 和40 。
(3)计算每位学生的总评成绩。
(4)计算该班级本课程的总平均成绩。
(5)计算处于优、良、中、及格、不及格的学生人数以及占总人数的百分比。其中100-90为优,89-80为良,79-70为中,69-60为及格,60分以下为不及格。
(6)按要求输出成绩在优、良、中、及格、不及格各区间的学生学号、成绩。-The student achievement calculation system s design with realizes (25) Request: (1) reads in the corresponding usual result, the midterm examination result and the terminal examinations result according to the class and grade according to the curriculum from the document. (2) three result are defined to the general appraisal result s percentage as the constant, occupies the overall result respectively 30 , 30 and 40 . (3) calculates each student s general appraisal result. (4) calculates this class and grade this curriculum the population mean result. (5) calculates the student population which is in superiorly, good, passes an examination, does not pass an examination as well as accounts for the total number of peop
