Log Message Timestamp

#include <iostream>
#include <string>
using namespace std;

void logMessage(string maessage, bool timestamp = false){
    if(timestamp){
        cout<<"[123456] "<< maessage;
    } else{
        cout<< maessage;
    }
}
// Write your function here

int main() {
    int mode;
    string msg;
    cin >> mode >> msg;

    if (mode == 0) {
        logMessage(msg);            // use default argument
    } else {
        logMessage(msg, true);      // enable timestamp
    }

    return 0;
}
