How can I serialize STL containers using Boost in C++?

How can I serialize STL containers using Boost in C++?

You can use the Boost Serialization library to serialize STL containers like vectors and maps. First, include the necessary headers.

What headers do I need to include?

You need to include <boost/serialization/vector.hpp> for vectors and <boost/serialization/map.hpp> for maps.

Can you show me a simple example?

Sure! Here's a basic example:

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/vector.hpp>
#include <fstream>

std::vector<int> myVector = {1, 2, 3, 4};

// Serialization
std::ofstream ofs("data.txt");
boost::archive::text_oarchive oa(ofs);
aa << myVector;

// Deserialization
std::vector<int> loadedVector;
std::ifstream ifs("data.txt");
boost::archive::text_iarchive ia(ifs);
ia >> loadedVector;

What if I want to serialize a custom class?

You can do that by implementing the serialize function in your class. Just make sure to include the Boost serialization headers.
