c语言实现，能够输入和查询客户存款取款记录。在客户文件中，每个客户是一条记录，包括编号、客户姓名、支取密码、客户地址、客户电话、账户总金额；在存取款文件中，每次存取款是一条记录，包括编号、日期、类别、存取数目、经办人。类别分为取款和存款两种。本系统能够输入客户存款或取款记录；根据客户姓名查询存款和取款记录。(c language, be able to enter and query the records of customer deposit withdrawals. , Each customer is a record in the customer file, including the number, customer name, withdraw the password, the customer address, customer phone account the total amount in the deposit file, each deposit is a record, including the number, date, category, access the number of managers. The categories are divided into two kinds of withdrawals and deposits. The system can enter the customer deposits or withdrawals records their deposits and withdrawals recorded according to the customer' s name.)

箱子最优分配——有n个集装箱要装上1艘载重量分别为c的轮船，其中第i个集装箱的重量为wi。最优装载问题要求确定在装载体积不受限制的情况下，将尽可能多的集装箱装上轮船，并找出一种装载方案 输入(Box optimal allocation- there are n containers to be loaded on a ship load of c, respectively, where the i-th container weight wi. Required to determine the optimal loading problem in the case of unrestricted loading volume, as many containers loaded on ships, and to find a loading program input)
