Visual C++ 2005 Home Edition

Hi all,

I am absolutely new to C++ so I downloaded Visual C++ 2005 Express Edition. And all of the tutorials I have found on the internet do not have the same GUI as this C++ edition, so I was wondering if I downloaded the right C++? I also tried running code snippets from the tutorials and it will give me build errors. I tried

Code:

---

#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])
{
        cout<<"Hello World\n";
}

---

To use cout you need to include the iostream header, which contains those functions. cout lives in the std namespace so you can either use std::cout or import the namespace.

Code:

---

#include <iostream>

int main()
{
    std::cout << "Hello World!\n";
}

---

Or

Code:

---

#include <iostream>

using namespace std;

int main()
{
    cout << "Hello World!\n";
}

---

Note that instead of \n you can use std::endl (end line) which is a stream manipulator, as follows:

Code:

---

std::cout << "Hello World!" << std::endl;

---

And make sure you select "Empty Project" in the project wizard, or you'll get weird errors.

Ok, so when I try to run the below code in an empty project it will say

"Unable to start program 'C:Learning Project.exe'
The system cannot find the specified file

Code:

---

#include <iostream>

using namespace std;

int main()
{
    cout << "Hello World!\n";

}

---

Now remember, I am completely new to C++ so I don't know whats goin on :D

I'd say you have some project configuration problems. It's attempting to launch a file that most definitely doesn't exist. Can't remotely solve that, though. Sorry.

What is everything I need to run the program.. a header file, .ccp?

Dont even need a header file. If you start with an empty project there should be nothing. Just add one .cpp source file, dump that code in, hit build and run. If that doesn't work, you definetely have some weird issue. try building it to different locations, see if that makes any difference.

When I try to build, it says 0 succeeded and 1 up-to-date... but when i click on "start debugging" then it says the same error :confused:

Try this:

New project.. Win32 Console App

The wizard comes up, click Application settings...

Check Empty Project..

Check Finish

Go to the solution explorer on the right..

Right click on Code.. Add.. New Item

Pick C++ File (.cpp) from the code section of the tree. Call it whatever you want (main.cpp is usually appropriate)

Then, you can start using some of the examples posted above.

P.S. - For learning and whatnot, if you're running it in the IDE, It's often helpful to add the line system("pause"); to the end of the program, so it doesn't flash on screen then go away.

I think that you should leave in:

#include "stdafx.h"

then type:

#include <iostream>

int main()
{
cout << "Hello World!";
return 0;
}

I think that the line "#include "stdafx.h" has something to do with including essential files necessary to code in the VC++ environment. Try that and let me know what happens.

Wrong. There are no "essential files necessary to code in the VC++ environment".

It's a project setting that Empty Project avoids that makes stdafx.h necessary. Which is why I always tell people to create empty projects.

What type of C++ are you trying to put in to the 2005 compiler? I'm sure that 2005 is based around .NET. Are you using VC++ 6 or ANSI C++ at all?

i also thought i saw a hello world above. have you tried using these examples

VC++6

//Hello World Example
#include<iostream.h>
using namespacestd;
int main()
{
cout<<"Hello World!" << endl;
return 0;
}

VC++.NET

#include "stdafx.h"

#using <mscorlib.dll>
#include <tchar.h>

using namespace system;

int_tmai(void)
{
Console::Writeline(S"hello world!");
return 0;
}
