Help with first program (Hello world)

I'm using the book "C++ Primer Plus 6e" by Prata and I feel like I'm following the instructions step-by-step.

I am using Microsoft Visual C++ 2010 Express. I start a new project and select "Win32 Console Application" and on the next screen I ensure that "Console application" is selected and I uncheck "Precompiled Header" and put a check in the box for "Empty Project."

Once the project is created, I make a new .cpp file and type the following code

Code:

---

#include <iostream>
int main()
{
    using namespace std;
    cout << "Come up and C++ me some time.";
    cout << endl;
    cout << "You won't regret it!" << endl;
    return 0;
}

When I try to build/debug I am greeted with this error message

Code:

---

1>------ Build started: Project: thisdoesntwork, Configuration: Debug Win32 ------
1>LINK : error LNK2001: unresolved external symbol _mainCRTStartup
1>c:\Users\Leewiz\Documents\Visual Studio 2010\projects\thisdoesntwork\Debug\thisdoesntwork.exe : fatal error LNK1120: 1 unresolved externals
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I did a quick google search and tried a few different things to no avail. Hopefully this forum can help!

Thanks in advance

The piece of code you wrote is ok.Something in your installation is not ok

You need to change your compiler settings. When you created your project you didn't select the proper project type. You selected a Win32 project instead of a console application.

I selected "Win32 console application". There is no other Console application. The only other "console application" option is "CLR Console Application" which throws in a whole bunch of extra stuff that I don't understand. All of the books I've looked at and instructions on the internet have a completely blank slate when they write this "Hello, World" program.

What might be wrong with my install? I installed it fresh off the microsoft website and changed nothing.

I figured it out from a reply on reddit! I had to add the source.cpp to the solution! I thought it was automatically in there. Hah! Thanks for the replies!

That should be correct.

I don't know, but it does look like your installation of Microsoft Visual C++ 2010 Express has a problem. You could try creating a new project using the same steps and see if there is any difference. If that still fails, then re-installing might be the way out.
