#includeThis code snippet demonstrates a simple logging function that takes a message and a value to log. It uses `std::put_time` to print the current time in a format suitable for logging, along with the message and value. The function uses `std::boolalpha` to print boolean values in a more readable format. The example then demonstrates using this function to log values of different types. The package library for cpp std log is the C++ Standard Library.#include #include #include #include #include #include #include template void log(const std::string& message, T value) { std::cerr << std::put_time(std::localtime(&std::chrono::system_clock::to_time_t(std::chrono::system_clock::now())), "%Y-%m-%d %H:%M:%S"); std::cerr << " - " << message << ": " << std::boolalpha << value << std::endl; } int main(int argc, char* argv[]) { int x = 42; double pi = 3.14159265358979323846; std::string message = "Hello, world!"; bool flag = true; log("x", x); log("pi", pi); log("message", message); log("flag", flag); return 0; }
