Assignment error with user defined vector container

[Raghuram N K]

Hi,
Following program compiles and executes successfully in windows with 
DevCPP compiler. When I compile the same in Linux with 'g++323' compiler 
I get following assignment error:

cannot convert `__gnu_cxx::__normal_iterator<DailyTemp*,
std::vector<DailyTemp, std::allocator<DailyTemp> > >' to `DailyTemp*'
in assignment

I believe the overloaded assignment operation is unable to recognize the 
iterator. Can anyone help me to over come this issue?

Thanks.

public:

//constructors

temp = x.get_temp(); return *this;
}

///member functions

};
bool operator<(DailyTemp a, DailyTemp b)
{
return a.get_temp() < b.get_temp();
