【问题描述】：
我目前正在从事一个涉及哈希表的项目。我已将文本文件读入符号结构的向量中，现在我必须将这些结构（实际上是对象）插入到哈希表中。我被赋予了一个特定的插入函数来使用，但是，我似乎无法让它工作。我已经包含了下面的插入函数以及我的 Driver.cpp 文件，该文件包含将文件读取到结构向量以及我尝试将其插入哈希表的尝试。
如果我出错的地方有任何帮助/反馈，我将不胜感激。
#include <iostream>

using namespace std;
struct Symbol
{
int type;
string name;
};
size_t hash(const string & key); //declaration of hashing function
int main()
{
/************ VARS ***************/
string line;
int line_count;
int table_size;
int increment;
/************ Vector of Symbols ***************/
vector<Symbol> symbols;
/************ HashTable of Symbols ***************/
HashTable<Symbol> hashtable; //precomputed to have 101 elements --> probably will change this to accomodate table size.
cout << "Opening file..." << endl;
usleep(2000000);
ifstream file;
file.open("symbols.txt");
if(!file)
{
cout << "System failed to open file.";
}
else
{
cout << "File successfully opened" << endl;
}
cout << "Please enter the table size for the Hash Table. (NOTE: It MUST be a prime number.)" << endl;
cin >> table_size;
for(Symbol temp; file >> temp.name >> temp.type;)
{
symbols.push_back(temp);
increment++;
}
//Just to test and see if its loading it correctly...
for(int i = 0; i < symbols.size(); i++)
{
cout << symbols[i].name << endl;
cout << symbols[i].type << endl;
}
for(int j = 0; j < symbols.size(); j++)
{
hashtable.insert(symbols); // Messing up here !!!!!!!!!!!!!
}
//cout << ::hash("hi") << endl;
}
size_t hash( const string & key )
{
size_t hashVal = 0;
for( char ch : key )
hashVal = 37 * hashVal + ch;
return hashVal;
}
在SeparateChaining.h 中插入函数：
bool insert( const HashedObj & x )
{
auto & whichList = theLists[ myhash( x ) ];
if( find( begin( whichList ), end( whichList ), x ) != end( whichList) )
return false;
whichList.push_back( x );
// Rehash; see Section 5.5
if( ++currentSize > theLists.size( ) )
rehash( );
return true;
}
bool insert( HashedObj && x )
{
auto & whichList = theLists[ myhash( x ) ];
if( find( begin( whichList ), end( whichList ), x ) != end( whichList ) )
return false;
whichList.push_back( std::move( x ) );
// Rehash; see Section 5.5
if( ++currentSize > theLists.size( ) )
rehash( );
return true;
}
作为 hashtable.insert(symbols) 完成时的错误：

您遇到了什么具体问题？

显然插入函数需要一个对象。我的向量是对象向量，但是当我尝试通过 hashtable.insert(symbols) 插入这些对象时，它会向我吐出一堆错误。现在我不知道是我只是插入了错误的东西还是以错误的方式做？ @Wyzard

@Wyzard 我很乐意发布错误，我只是想知道我是否正确地执行了此操作。我在上面重新发布了与他们的情况相匹配的以下错误。
