How can I use the Boost library in C++?

The Boost library provides a wide range of functionalities. Are you looking for specific features or general usage?

I'm interested in smart pointers and file system operations.

For smart pointers, you can use boost::shared_ptr or boost::unique_ptr. For file system operations, check out boost::filesystem. Would you like code examples?

Yes, please provide examples for both.

Sure! Here's a simple example for shared_ptr:

#include <boost/shared_ptr.hpp>

boost::shared_ptr<int> ptr(new int(10));

And for filesystem:

#include <boost/filesystem.hpp>

boost::filesystem::path p("/path/to/file");
if (boost::filesystem::exists(p)) {
    std::cout << "File exists!";
}
