System time

[Nelphin]

how can i get the actual system time to cout?

[Tytrin]

# include <ctime> should be the library you need, then
long sys_time=time();

cout << sys_time;

that should do it but that might output the time in ticks... but the ctime library should have all the necessary functions.

i tried to implement ur example snippets in a function:

void addtolog(string logtext)
{
   ofstream logfile ( "logfile.txt",ios::app );
   long sys_time=time();
   logfile<<"\n"<<sys_time<<" "<<logtext;
   logfile.close;
}

but i get an error that says:

"too few arguments to function 'time_t time(time_t*)'"

Try this:

Not sure if it'll work, but it's worth a try.

thanks, this works now:

void addtolog(string logtext)
{
    time_t rawtime;
    struct tm * timeinfo;

    time ( &rawtime );
    timeinfo = localtime ( &rawtime );
    ofstream logfile ( "logfile.txt",ios::app );
    logfile<<"\n"<<asctime (timeinfo)<<logtext;

}
