How can I implement error logging in C++11?

You can implement error logging in C++11 using the <iostream> library for console output or by creating a custom logging class.

What features should my logging class have?

Your logging class should include features like log levels (info, warning, error), timestamps, and the ability to log to files.

Can you show me a simple example of a logging class?

Sure! Here's a basic example:

#include <iostream>
#include <fstream>
#include <string>

class Logger {
public:
    enum LogLevel { INFO, WARNING, ERROR };
    void log(LogLevel level, const std::string &message) {
        std::ofstream logFile("log.txt", std::ios_base::app);
        logFile << getLevelString(level) << ": " << message << std::endl;
    }
private:
    std::string getLevelString(LogLevel level) {
        switch (level) {
            case INFO: return "INFO";
            case WARNING: return "WARNING";
            case ERROR: return "ERROR";
            default: return "";
        }
    }
};

This class logs messages to a file with different log levels.

How can I test if my logging works correctly?

You can test your logging by creating instances of the Logger class and calling the log method with different log levels and messages.
