std::fstream PrimeFile ("Primes.txt", std::ios_base::out);

PrimeFile << n << std::endl;

More easily:

std::ofstream primeFile("primes.txt");
primeFile << n << std::endl;

I wanted to send my friend the .exe so I looked up in my projects file and found it but when he tries to open he gets this crap :

This application has failed to start because the application configuration is incorrect.

If you're using Visual C++, he might need the runtimes.

If you're using MinGW/GCC, I have no clue what the requirements are.
