C++, STL Programming

Hi,
I am new to STL programming, need help on how to find an element especially from vector of user defind type objs.

myclass.h
--------------------------------
Class myclass {
private:
string md_name1, md_name2;
int md_usr_id;
public:
myclass();
~myclass();
};


vmain.cpp
------------

int main()
{
vector<myclass>::iterator lv_find_result;
vector<myclass> lv_vecMyclass_Obj;
//populate value, say (a1, a11, 1) (a2, a22, 2) (a3, a33, 3) for md_name1, name2, id respectively....

//now want to find a particular name say a55 using find algorithm
lv_find_result = find (lv_vecMyclass_Obj.begin(), lv_vecMyclass_Obj.end(), ??);

How should i fill 3rd arg in find algo such that it will find name a55?

return 0;
}

Define the "<" and "==" operators for your class to use the find() algorithm. The third argument is simply a myclass object to which the vector members are compared.

For C++ STL programming I find this book to be an invaluable reference.

markkuk and tabish121 thanks for your help and info. Implemented "==" operator in my class.
