operator overloading & STL

[solartimba]

Basic question: I am using STL for the first time, and I want to put
the following class into a vector. What member functions/overloaded
operators do I have to include? In general, when using STL, how do I
answer this question?

//******************
class cStockPrice
{
private:
string date;
float price;
public:
cStockPrice() : date("NA"), close(0)
{ }
void getPrice(string tmpDate, float clse)
{ date=tmpDate;
close=clse;
}
}; //end of cStockPrice

Elements of std::vector<> just have to be default constructible
and copyable. You define a default c'tor, and the compiler-
generated copy c'tor will work just fine for your class, so it
should work as is.

[...]

Use the table which states requirements on T for various
containers.

None. Your class just has to be copyable, which your example below is.

Get a good book about it.

//******************
class cStockPrice
{
private:
string date;
float price;

Wasn't that float member meant to be named 'close'?

Questions answered in other replies. However to look up what the STL expects
and what you can do with it see;
