[C++]sales-reporter

1.使用前需要把数据文件放置在exe程序同一文件夹内。2.数据文件内容可修改，有且仅有8对数据，否则会报错（已预置sales.txt文件，格式可参照修改，第一列为itemNumber，第二列为对应的unitePrice）3.双击exe运行，根据提示输入数据文件名称，存放结果数据文件名称，salesperson lastname（内置z1-z10），item number，quantity。4.salesperson lastname不得超出z1-z10，否则报错。5.程序作用：<span style="white-space: pre;"></span>根据销售项目及单价（文件形式），输入相应的销售项目和数量，自动生成每个人的销售报告（文件形式）。
