How do I set up logging in a C++ and Java application?

How do I set up logging in a C++ and Java application?

To set up logging in C++, you can use libraries like spdlog or Boost.Log. In Java, you can use Log4j or SLF4J.

Can you give me a simple example of using spdlog in C++?

Sure! Here's a basic example:

#include <spdlog/spdlog.h>

int main() {
    spdlog::info("Hello, {}!", "world");
    return 0;
}

What about a basic example using Log4j in Java?

Here's a simple Log4j example:

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class Main {
    private static final Logger logger = LogManager.getLogger(Main.class);

    public static void main(String[] args) {
        logger.info("Hello, {}!", "world");
    }
}

Are there any best practices for logging in these languages?

Yes, some best practices include:

1. Use appropriate log levels (DEBUG, INFO, WARN, ERROR).
2. Avoid logging sensitive information.
3. Use structured logging for better analysis.
