系统运行过程如下：

首先，通过系统产生或手工输入方式，产生数据源文件（数据源.dat)，包括：学号，姓名，各科成绩。

其次，构造对象数组，从"数据源.dat"文件中读入数据，并赋于各公有数据成员。

第三，通过调用系统各函数，实现数据分析，得出结果。过程数据记录在"过程数据记录.txt"文件中，以备查用。

第四，成功获得综合策评结论，并将其输出到“综合策评表.txt”文件中。-System runs as follows: First, through the system to produce or manual input method, resulting in the data source file (data source. Dat), including: Student ID, name, subjects results. Second, construct an array of objects, from the " data source. Dat"　file, read into the data, and assigns of all public data members. Third, by calling the system function, data analysis and outcome. Process data recorded in the " process data records. Txt"　file to use for future reference. Fourth, the successful conclusions of an integrated policy assessment, and its output to the " comprehensive policy evaluation form. Txt"　file.
