Question

当我尝试编译我的类时，我收到此错误。我确保有正确的函数原型和变量，希望有人可以帮我找出问题

rdd1:
id1  A
id2  B
id3  C

这是我的头文件

id1 A A
id1 A B
id1 A C
id2 B A
id2 B B
id2 B C
id3 C A
id3 C B
id3 C C

这是我的源文件

我有点迷失在什么问题上

Answer 1

此：

int getTransID()        { return transID;  }

与你的班级无关，它是一个全球性的职能。

你的意思是：

int Transaction::getTransID() { return transID;  }

此外，该功能（以及其他吸气剂）应该const表示他们不会修改对象。

在此范围内未声明“变量”
