What are some examples of using C++ libraries?

C++ has many libraries. For example, the Standard Template Library (STL) provides data structures like vectors and maps.

Can you give me a specific example of using STL?

Sure! Here's a simple example: using a vector to store integers and then iterating through it:

#include <iostream>
#include <vector>

int main() {
    std::vector<int> numbers = {1, 2, 3, 4, 5};
    for (int num : numbers) {
        std::cout << num << " ";
    }
    return 0;
}

What about using Boost libraries?

Boost provides many useful libraries. For instance, Boost.Asio is great for network programming. You can handle asynchronous I/O.

Can you show me a simple Boost.Asio example?

Certainly! Here's a basic example of a Boost.Asio TCP client:

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

int main() {
    boost::asio::io_context io;
    boost::asio::ip::tcp::resolver resolver(io);
    auto endpoints = resolver.resolve("localhost", "8080");
    // Further code to connect and communicate...
}
