C++ 访问向量元素时的分段错误

这是我的节目，一个星球大战问答游戏 当我运行该程序时，它到达cast[5]部分，然后崩溃（分段错误）

因为“赫特人贾巴6”不是由两个字符串和一个数字组成的

因此：

myFile>>插曲获取一个字符串，而不是
int插曲；
在调试器中运行此操作！单步执行代码，观察变量。将输入文件格式化为代码；这样，就不清楚行与行之间是否有空白行，是否有名称。
赫特人贾巴
这是一组名称，哪个是
第一个，哪个是
一个是
last
？让我放大@n.m.的评论。当遇到这一行时，'Jabba'是你的名字，'the'是你的第二个名字，你试着读
Hutt
，因为
int
var
插曲
失败了，流现在处于失败模式，因此不好，while循环中断，没有更多的数据插入到后面最后一段数据（jabba）是不完整的，在
插曲
中包含不确定的内容，驻留在元素

中。孩子们，这就是为什么我们检查IO操作而不认为它们成功的原因。@WhozCraig还值得记住，以防万一，我们通常认为关于名称的事情是错误的。
