问题描述

我正在尝试编写程序以读取库存文件并创建库存报告.该报告将包含零件号，价格，现有数量，重新订购点，最小订购量和订购数量.当手头数量低于重新订购点时，将计算订购数量.计算方法为再订购点和最小订购量之和减去现有数量.

每当我运行程序时，我得到的只是
读取数据时出错
报告结束"

我究竟做错了什么???救命！

Im trying to write a program to read an inventory file and create an inventory report. The report is to contain the part number, price, quantity on hand, reorder point, minimum order, and order amount. The order amount is calculated when the quantity on hand falls below the reorder point. It is calculated as the sum of the reorder point and the minimum order minus the quantity on hand.

Whenever I run the program though, all I get is
"Error reading data
End of Report"

What am I doing wrong??? Help!
