Looping and caling in a text file C++

Hi ,

I am trying to create a loop to call in the entries from the text file named Set.
The entries of Set.txtare :

1 2 3
2 4 5 
and so on .. (64 such combinations)

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

// 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:confused:

I guess you are saying you want STL object containers, which contain other objects, which if they are your lines, would contain three objects, which look to be int. In C++, less char and str*(). string - C++ Reference Not seeing anything like open and read, error checking/exception catching for short input, not digits?
