When I first starting using C++, I used Microsoft Visual C++ 2003, an it worked just fine for me. Of course I was also in a high school class, so I had an instructor. I've used Dev-C++ before, and from what I recollect, it was fine for starting out. I'm sure a beginner won't notice the features that it's missing until he/she moves on to something more complex.

Ok, so I downloaded that Visual studio, and I tried to make a "Hello World" program. It didn't work. it just gave me a bunch of errors.

 c Syntax (Toggle Plain Text) 
/*my hello program with comments*/
#include <iostream>
using namespace std;
 
int main ()
{
	cout <<"Hello World!";//Prints Hello World
	cout <<"I'm a C++ Program!";//Prints I'm a C++ program	return 0;
}
/*my hello program with comments*/
#include <iostream>
using namespace std;

int main ()
{
	cout <<"Hello World!";//Prints Hello World
	cout <<"I'm a C++ Program!";//Prints I'm a C++ program	return 0;
}

there is my code. then i click the build tab, then Build Hello World, and this comes up

What is wrong?

return 0; needs to be on a new line. Other than that I really don't see a reason it should fail. Are you sure that's all your code?

H0ndaM4n · May 22nd, 2008, 5:06 PM

that is all of my code.

Soulstorm · May 26th, 2008, 12:17 PM

The above code is correct, and I don't see any reason it should fail, even if you don't place "return 0" in a new line. I would assume there is something wrong with your Visual Studio installation.

And please use code tags next time, as it makes your code much easier for us to read.

g++ will work for u
u can get it in MinGW for windows and for linux, there are many packages available
u can also configure it with eclipse and harness the feature of eclipse

I'm using microsoft visual C++ as a compilor, but i'm coding in C++, not visual C++. Could that be the problem? Also, on one of the little tutorials that came w/ the program, it drug me thru some thing where i had to make a class and stuff, do i need to do that?

Visual C++ is just the name of the IDE, the language is still C++. "Visual" is sort of the branding used by Microsoft: Visual C++, Visual C#, Visual Basic, and Visual Web Developer make up Visual Studio. I'm really not sure how this problem could be though; I tried it in Visual Studio and it worked fine for me.

My guess is that you've paraphrased your code, and not posted the actual code you fed to your compiler. Based on that guess, you probably left out a character somewhere and/or commented out something you didn't intend.

what type of project did you create? you should have created an "Empty Project". then you should go to the menu and choose "Project" > "Add New Item ...". Then you should choose Visual C++ as the category and "C++ File (.cpp)" from the right side. Then paste your code into that file and build.
