How do I serialize the vector of an object in c++?

suppose I have the following class

C++

#ifndef TRAY_H
#define TRAY_H
#include "EGG.h";
#include "FLOUR.h";
class TRAY
{
double price;
std::vector<EGG> eggs;
public:
TRAY(int number);
~TRAY();
double getTotalPrice();
std::vector<EGG> getEggs();
};
#endif

How would I go about serializing a TRAY object's eggs inc c++ using sqlite3?

One other question I have is if it is possible to serialize an object that has no attributes, i.e. it has only functions.

You can serialize the object; with or without any attribute or property. Where are you actually stuck?

Yes I was.
So in the TRAY.cpp file, eggs are pushed into the eggs vector.

I have no problems serializing an object's attributes so long as they are ints or strings, but I was stuck when it came to data structures like vectors and arrays. I thought of making variables for each object in the vector but I didn't know how to go about it.

You would use templates here, since you don't know what you might be pushing into the vector.

Suppose I'm pushing eggs into the vector. Could you please provide an example to shed some more light on this?

You may either write your own code for serializing a vector (which in turn serializes all the items of the vector) or use, for instance, boost::serialization[^].
