学生成绩核算系统的设计与实现：
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。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 。计算每位学生的总评成绩。计算该班级本课程的总平均成绩。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。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
-Student achievement Accounting System Design and Implementation: by class by course read from the file corresponding normal results, midterm examinations and final examination results. Three results on the percentage of total grades are defined as constants, the total score of 30 , 30 and 40 . Calculate each student' s total grades. Calculate the class average score of the course. Calculation is excellent, good, in passing, the number of students fail and the percentage of the total number. 100-90 which was excellent to good ,89-80 ,79-70 ,69-60 as the passing of 60 points or less is failing. Required output results in excellent, good, in passing, failing the students to learn the range of numbers, results
