What is the Boost library in C++?

The Boost library is a collection of peer-reviewed portable C++ source libraries that extend the functionality of C++. It provides support for tasks and structures such as linear algebra, multithreading, and more.

How do I install the Boost library?

You can install the Boost library using package managers like vcpkg or Homebrew, or by downloading it from the Boost website and building it from source.

Can you give me an example of using Boost in a project?

Sure! For example, you can use Boost's smart pointers to manage dynamic memory safely. Here's a simple code snippet:

#include <boost/shared_ptr.hpp>

class MyClass {
public:
    void display() { std::cout << "Hello, Boost!" << std::endl; }
};

int main() {
    boost::shared_ptr<MyClass> ptr(new MyClass());
    ptr->display();
    return 0;
}
