VC++开发的成绩分布图源程序，附实验报告文档，主要的功能是通过给定的一组成绩数据绘制出成绩的分布图（包括直方图和圆饼图）。这里没有用到数据库，因为是一个简单的成绩分布图，而用数据库的话在转到另一台机子上还要重新建表，对于学生信息也要涉及到录入问题，不容易实际操作，所以本示例采用了更为方便的通过手动录入数据或者是从文件（txt格式文本文档，第一个数为总人数，其余为分数，分数之间用逗号隔开）导入数据两种方式绘制出其统计图。-The achievement distribution source VC++ developed attached lab report document, the main function is to draw out a diagram of the distribution of results (including histograms and pie charts) by a given set of performance data. Here did not use the database, because it is a simple achievement maps, database Go to another machine, but also re-built table for student information should be related to the input problem, the actual operation is not easy, so this example with a more convenient two ways to import data to map out its statistical manual data entry or from a file (txt format text documents, the first number to the total number of the remaining fractional fraction separated by commas) Figure.
