c++封装一个Log类

#include <iostream>
class Log {

public:
    const int LogLevelError = 0;
    const int LogLevelWarning = 1;
    const int LogLevelInfo = 2;
private:
    int m_LogLevel = LogLevelInfo;

public:
    void SetLevel(const int level) {
        m_LogLevel = level;
    }

    void Warn(const char* message) {
        if (m_LogLevel >= LogLevelWarning)
            std::cout << "[WARN]:" << message << std::endl;
    }
    void Error(const char* message) {
        if (m_LogLevel >= LogLevelError)
            std::cout << "[Error]:" << message << std::endl;
    }
    void Info(const char* message) {
        if (m_LogLevel >= LogLevelInfo)
            std::cout << "[Info]:" << message << std::endl;
    }
};

int main() {

    Log log;
    log.SetLevel(log.LogLevelError);
    log.Error("error message");
    log.Info("info message");
    log.Warn("warn message");

    return 0;
}
