How do I format logging in C++?

How do I format logging in C++?

In C++, you can use libraries like spdlog or log4cpp for structured logging. What specific formatting do you need?

I want to include timestamps and log levels in my logs.

You can format your logs by using a pattern like "%Y-%m-%d %H:%M:%S [level] message". Would you like a code example?

Yes, please provide a code example.

Here's a simple example using spdlog:

#include <spdlog/spdlog.h>
#include <spdlog/sinks/basic_file_sink.h>

int main() {
    auto logger = spdlog::basic_logger_mt("basic_logger", "logs.txt");
    logger->set_pattern("%Y-%m-%d %H:%M:%S [%l] %v");
    logger->info("This is an info message");
    return 0;
}
