Osnovni problem pri prevajanju v Visual Studiu

Pozdravljeni.

Sem zacetnik v Visual Studiu, pa tudi v programiranju.
Pri preprostem programu mi javlja napako: 1>.\test.c(1) : fatal error C1083: Cannot open include file: 'iostream.h': No such file or directory

To pomeni, da mi manjka ta knjiznica? Kako jo nalozim?

Sem naredil, pa mi javlja:
1>C:\Program Files\Microsoft Visual Studio 8\VC\include\cstdio(25) : error C2143: syntax error : missing '{' before ':'
1>C:\Program Files\Microsoft Visual Studio 8\VC\include\cstdio(25) : error C2059: syntax error : ':'
...
1>C:\Program Files\Microsoft Visual Studio 8\VC\include\cstdlib(20) : error C2059: syntax error : ':'
1>C:\Program Files\Microsoft Visual Studio 8\VC\include\cstdlib(21) : error C2143: syntax error : missing '{' before ':'
...

Sj pravm, toj čist osnovn program: (blush)

 #include <iostream>

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

pa če hočeš uporabljat direktno cout, cin etc... moreš dat tak

#include <iostream>

using namespace std;

...
