Hiii , I am trying to create a loop to call in the entries from the text file named Set. The entries of Set.txt are : 1 2 3 2 4 5 and so on .. (64 such combinations)[/CODE] it basically means the first combination for testing is 1 2 3 and next has to be 2 4 5 and so i have 64 such entries defined in set my test files are located in D://data// and are named tst_data1 to tst_data64. i created a loop for test set but its incorrect Code: // loop for test samples char basefilename[] = "D://data//"; char , testFilen[160], numiChar[10]; for (int i=1; i<=64; i++) { strcpy(basefilenme, "D://data//"); strcat(testfilename, Set[]); if (testfilenme=='_' && testfilenme[i+1]=='\0'){ strcat(testfilename, numiChar); strcat(testfilename, "_"); break; } strcat(testfilename, ".txt"); cout<<testfilename<<endl; please correct me how can i call the Set .txt and how to define it. thanks
I'm not sure what you're asking about. I *see* that want your file names to look like d://data//tst_data1...tst_data64 is that right? If it is, then using sprintf would be a lot eaiser. Code: for(i=1; i <= 64; ++i) { memset(buffer, 0, sizeof(buffer)); // clear out any trash characters sprintf(buffer, "d://data//tst_data%d", i); // tst_data1 - tst_data64 } If you're building these as 64 separate file names to open, then in this loop try something like Code: FILE *fp; loop(...) { // build string as above if((fp = fopen(buffer, "r")) != NULL) { char line[100]; while(fgets(line, sizeof(line), fp) != NULL) { // do something with line } fclose(fp); } } if each digit on your lines is separated by a space, then you can use sscanf to pick them off line. Code: int digit1, digit2, digit3; while(fgets(line, sizeof line, fp) != NULL) { if((sscanf(line, "%d %d %d", &digit1, &digit2, &digit3)) != 3) // error parsing line else // do something with digit1, digit2, and digit3 } If it just one integer, then change the sscanf call to Code: if((sscanf(line, "%d", &number)) != 1) // error parsing line else // do something with number Hope that helps
