C++ code to make your application a trial version

{

time_t rawtime, end;

struct tm * endinfo;

double dif;

time ( &rawtime );

endinfo = gmtime ( &rawtime );

endinfo->tm_year = year-1900;

endinfo->tm_mon = Month-1;

endinfo->tm_mday = Day;

end = mktime ( endinfo );

dif = difftime(end, rawtime);

if (dif less than 0)

printf("\nTrial Version Expired \n");

}

Year, Month and Day are all integers. Enter your Date on which you want the application to be expired.
