How come the two dates printed out by this program are the same?
Code:#include <stdio.h> #include <stdlib.h> #include <time.h> int main() { time_t t, t2; struct tm* current_time, *other_time; time(&t); t2 = t + (11 * 24 * 60 * 60); current_time=gmtime(&t); other_time=gmtime(&t2); printf("%d %d %d\n", current_time->tm_mon, current_time->tm_mday, current_time->tm_year+1900); printf("%d %d %d\n", other_time->tm_mon, other_time->tm_mday, other_time->tm_year+1900); return 0; }
"gmtime" returns an internally allocated structure which gets overwritten on each successive call. In other words, you need to copy the data before you call the function again.Originally Posted by Boxknife

Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Thanks!
