"endl" causes "C1001" error

Question

My code is a basic HelloWorld but fails to compile when I use cout<<endl.

I'm using Microsoft visual studio fresh download and created a console application for my first test project.

    // Test1ConsoleApplication.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <string>
#include <iostream>
//#include <ostream>


using namespace std;


int main()
{
    string s = "hello world!!";
    cout << "lets see: " << s << endl;
    return 0;
}

It generates a

"C1001" at line 1.

Replacing "endl" with ""\n"" works though.

The example given compiles just fine. I suspect there is an error in stdafx.h — Jive Dadson, Jan 20 '18 at 06:56

You don't need the precompiled header #include <stdafx.h> so you can safely get rid of it. Also get rid of using namespace std; because it pollutes the global namespace. Try something like this. There's no reason it shouldn't work.

#include <string>
#include <iostream>

using std::string;
using std::cout;
using std::endl;

int main()
{
    string s = "hello world!!";
    cout << "lets see: " << s << endl;
    return 0;
}

In Visual Studio you can disable use of the precompiled header in the project settings.

I do not see what the problem is. Both options compile and execute for me. RexTester cppOnline

// Test1ConsoleApplication.cpp : Defines the entry point for the console application.
//
//#include "stdafx.h"
#include <string>
#include <iostream>
//#include <ostream>


using namespace std;


int main()
{
    string s = "hello world!!";
    cout << "lets see: " << s << endl;
    cout << "lets see: " << s << "\n";
    return 0;
}

So idk what was causing the error but it was fixed after pasting imports to the "stdafx.h" header file and then delete them...
