#include <iostream>
#include <fstream>
#include "stdafx.h"
using namespace std;
int main() 
{
    ofstream myfile;
    myfile.open("example.txt");
    myfile << "Writing this to a file.\n";
    myfile.close();
    return 0;
}

I am trying out basic file handling in c++ using visual studio 2017, can't seem to use the class fstream

what should I do ?

Turn off pre-compiled headers, remove #include "stdafx.h" – john

The compiler ignores everything before #include "stdafx.h" so move that line above the other include directives.
