Useful Sample C++ Codes

 

estimating time	============ double dtime() { #ifdef LINUX     struct timeval tv;     gettimeofday(&tv, NULL);     return ((double)tv.tv_sec + ((double)tv.tv_usec*1.0e-6)); #else //VS studio     time_t ltime;     time(&ltime);     struct timeb tmb;     ftime(&tmb);     double sec = (double)(ltime);     double milisec = (double)tmb.millitm;     return (sec + milisec/1000);  #endif } ============
Read index files	std::vector<int> test_image_class_order; FILE *f = fopen(indexFile, "r"); char imgname[255]; int imgClass = -1; while (fscanf(f, "%s %i", imgname, &imgClass) > 0) {     string iname(imgname);     test_image_class_order.push_back(imgClass);     test_image_name.push_back(iname); // filename } fclose(f);
