Why do I get the following compiler error when adding an object to a vector, which its data member is referencing another object?
The compiler error:
Error 1 error C2582: 'operator =' function is unavailable in 'Product' c:\program files\microsoft visual studio 8\vc\include\xutility 2726
In the program I collect all data before I create a new Product object,
then, creating the object and passing all data to the constructor:
the problem is in the push_back(p) line,
vector<Product> productsArr;
vector<string> categoriesArr;
class Product
{
private:
string m_code;
string m_name;
string& m_category_ref;
string m_description;
double m_price;
Product();
public:
Product(const string& code,const string& name,string& refToCategory,
const string& description, const double& price):m_category_ref(refToCategory)
{
m_code = code;
m_name = name;
m_description = description;
m_price = price;
}
}
void addProduct()
{
string code,name,description;
double price;
int categoryIndex;
getProductData(code,name,price,categoryIndex,description);
Product p(code,name,categoriesArr[categoryIndex],description,price);
productsArr.push_back(p);
}
the line from the xutility:
// TEMPLATE FUNCTION fill
template<class _FwdIt, class _Ty> inline
void __CLRCALL_OR_CDECL _Fill(_FwdIt _First, _FwdIt _Last, const _Ty& _Val)
{ // copy _Val through [_First, _Last)
_DEBUG_RANGE(_First, _Last);
for (; _First != _Last; ++_First)
*_First = _Val;
}
