C++ Boost Libraries Tutorial

What Are Boost Libraries?

Boost provides solutions for tasks like file I/O, data structures, and multithreading. Many Boost libraries are included in the C++ Standard Library.

Installing Boost

1. Download Boost from the official website.
2. Extract the archive and run bootstrap.bat (Windows) or bootstrap.sh (Linux).
3. Build Boost using b2.

Example: Using Boost Libraries

Boost Filesystem

#include <boost/filesystem.hpp>
#include <iostream>

int main() {
    boost::filesystem::path p = "/path/to/directory";
    if (boost::filesystem::exists(p)) {
        std::cout << "Directory exists." << std::endl;
    } else {
        std::cout << "Directory does not exist." << std::endl;
    }
    return 0;
}
                

Benefits of Boost Libraries

• Provide advanced functionality missing from standard C++.
• Portable and platform-independent.
• Highly optimized and reliable.
