[討論] 一個小問題

[t27935912 (david)]

這是我的operator overload ==


      bool operator == (const iterator& i) const {
        if(i._node == (*this))
          return true;
        else
          return false;

     }

這是我的erase部分


 bool erase(const T&x) {
     for(size_t i=0; i<_size; i++)
     {
       iterator it;
       it++;
       if(it._node == x)
       {
         iterator it(T* ptr);
         return true;
       }
     }
     return false;
   }


compile後出現以下error


In file included from adtTest.h:42,
                 from adtTest.cpp:10:
../../include/array.h: In member function ‘bool Array<T>::erase(const T&) [with T = AdtTestObj]’:
adtTest.h:90:   instantiated from here
../../include/array.h:149: error: no match for ‘operator==’ in ‘it.Array<AdtTestObj>::iterator::_node == x’
make[1]: *** [adtTest.o] Error 1
make: *** [main] Error 2


不知道是為何
請大家幫忙一下
謝謝!!

→ djshen:it._node跟x的型態?
推 wmin0:_node是T* x是T
推 timrau:T*和iterator沒辦法比較啊。也許該
→ timrau:if(i._node == _node)之類的
→ t27935912:感謝!!!!
