匹配txt文件并计算单词C++的数量？

Question

嗨我是C++的新手，很难用这段代码来帮助你排序，因为我不知道如何解决这些错误。 当我运行我的代码，它抛出了3个错误

on line 116:error C2679: binary '=' : no operator found which takes a right-hand operand of type 'std::_Vector_iterator<_Myvec>' (or there is no acceptable conversion)

可以请告诉我如何纠正代码。在几个部分代码如下下面

代码：

class Word 
{ 
public: 
string name; 
int hits; 
Word() 
{ } 
}; 

Update : /***** Prototypes *****/

{

string strBanned = "banned.txt";

Answer 1

你试图分配vector<Word>::iterator直接Word对象，反之亦然。你需要从迭代器使用*运算符取消引用Word：

oneWord = *itBanned; 

和

*itBanned = oneWord;
