.net stuff hello world program

[drewdaman]

hello all.. i'm used to msvs6... not too familiar with .net. i tried to make a hello world program in .net, but surprise surprise, it doesn't work! thats the code, coudln't be simpler, but it doesnt' understand what "cout" means!!


#include <iostream>

int main(){

cout << "hello world";
}


would be great if someone could let me know whats going on!
thanks,
drew

sorry.. i forgot to mention a few things.

using the line "using namespacestd" solves the problem on some computers, but not on all of them. i heard that there were some changes in .net so that printing to the console could be done in the same way from vb, c++, C# etc. is that true? and if so, how do you do it?

thanks!

Are you talking about C++, Managed C++, or C#?

If you are talking about C++, you can still stick with cout (as long as the ANSI commitee doesnt change C++ standard).

There are 2 ways to solve your problem ...

#include <iostream>

using namespace std;

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

or

#include <iostream>

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

thanks!

just curious tho.. why did they feel they needed to change this? is this common to c#, vb .net etc too? or is it just for c++? and how come "using namespace std" doesn't work on all computers?

thanks again,
drew

I am not sure where you heard that from but so far I have no problem with "using namespace std" on different computers.

C++ is not a propriety language. It means that C++ is not owned by any company, and its standard is set by a non-profit ANSI commitee (not Microsoft).

If you are talking about Managed C++, C#, and VB, then you should ask Microsoft why they keep on changing stuffs.
