我正在尝试将我的文本文件读入我制作的类对象的向量中:
cust_id first_name last_name company_name address city state zip
101 James Butler 6649 N Blue Gum St New Orleans LA 70116
102 Josephine Darakjy Chanay, Jeffrey A Esq 4 B Blue Ridge Blvd Brighton MI 48116
103 Art Venere 8 W Cerritos Ave #54 Bridgeport NJ 08014
104 Lenna Paprocki Feltz Printing 639 Main St Anchorage AK 99501
……...
如您所见,company字段的列包含几个空字段,因此我的向量包含很多零。不确定如何执行此操作。我已经检查了我们的社区,但没有发现任何东西。如果有人可以快速浏览一下C ++,那么我对C ++还是陌生的。谢谢。提示也可以。
