Hello!
The title basic describes my problem, and I'm struggling to work out how to do such a thing, I've looked at stringstreams amongst other ways but cannot get it to work.
This is the code to my program, its a word-list generator.

cout << "That file does not exist. Please re-enter the file location: " << endl;
cin >> iDirectory;
}
ofstream ouFile ("output.txt");
clock_t begin=clock();
while (!myFile.eof())
{
if(a==1) {
myFile >> wBuffer;
wBuffer[0] = toupper(wBuffer[0]);
ouFile << wBuffer << "1" << endl;
}

After
ofstream ouFile ("output.txt"); I want to check whether Output.txt exists, then, if it does, create Output1.txt, then Output2.txt and so forth, if it doesn't exist, create Output.txt as standard.
Currently, thats where I think it should be placed, but maybe not, all help is appreciated.
