本演示程序演算约瑟夫环问题，人数n应为任意的，首先应输入一个值赋给初始报数上限m，程序应能自动保存出列人的序号和将出列的人所持的密码赋给m，再次作为报数上限，如此循环，直至所有人都出列为止。-The demo program Joseph Central calculus problem, the number n should be arbitrary, we must first enter a value assigned to the initial reported that the maximum number of m, the procedure should be able to automatically save a list of the serial number of people and held out the password given to m, again as reported maximum number of such cycles, until all that far out.

是我应我们学校学工部做的软件,其主要是解决想我们学校这样的条件--各个办公室之间还没有建立联网,而且学校分为两个校区（又不在一个城市). 　　因此，学工部每年的学分登记工作都很麻烦．每学年初，学工部要把当年发布的学分评测规定发到各系，学年末又要把从系里面提交的学分表收齐,然后手工登记,非常的麻烦.有时是系里面的学分报表太乱，有些资料丢失，要么是，系里面把各年的学分评测规定弄混，经常搞的他们一头雾水，于是为他们就请我做这个系统. 　　这个系统的工作流程是，每个学年初，学工部输入当年的学分评定规定，然后到处成为学分评测数据，然后Copy给各个系，各个系在每个学年中，输入新的专业，年级，班级和新生的资料，然后登记学分评测的纪录和考试的成绩．当学年末到了，各系把党学年的数据导成数据库，然后copy给学工部，学工部就可以用电脑纪录所有的学分纪录． -should I do our school among a software, it is our resolve to schools such conditions-- every office has not yet been established between the network and the school is divided into two campuses (not in a city). Therefore, each of the credit among a registration work very troublesome.
