StrBlob.h 头文件报错

[kagtag]

参考文件为 https://github.com/Mooophy/Cpp-Primer/blob/master/ch15/ex15.34.35.36.38/StrBlob.h
运行系统为windows 7 professional
IDE为 Visual Studio 2015 professional

出现了两个错误

1. StrBlob类的两个成员函数 StrBlobPtr bebin()和 StrBlobPtr end()在类外定义处报错
   Declaration is incompatible with StrBlobPtr StrBlob::begin()
   Declaration is incompatible with StrBlobPtr StrBlob::end()

2. StrBlobPtr类中构造函数无法访问StrBlob类私有成员data
   StrBlobPtr(const StrBlob &a, const size_t sz=0):wptr(a.data),curr(sz){}
   报错信息为
   member StrBlob::data declared at .... is inaccessible.

使用类型的时候需要知道其定义(类结构)，只有使用类指针的时候前置声明就够用了(class Type)
