my "hello world" whats wrong

[Guest]

heres my code,
//////////////////////////////////////////////////////////////////////
#include "iostream"
#include "holla.h"

//////////////////////////////////////////////////////////////////////
using namespace std;
int main();
{
cout;"halo2"


return 0;
}
it keeps saying missing function header what do i have to do? MAJOR NOOB!

Code: Select all

cout<<"hello";

what about the semicolon after main? there shouldn't be one

Code: Select all

int main() <- no semicolon
{
     ...
}

edit:
@Armen138 damn, you were faster

[Guest]

#include<iostream>

"Guest" was right.

Code: Select all

//////////////////////////////////////////////////////////////////////
#include <iostream.h> // I changed it
#include "holla.h"

//////////////////////////////////////////////////////////////////////
// I removed the namespace
int main(void) // Added void, didn't know it was called a semicolon :?
{
cout<<"halo2"; // Here I've added ;


return 0;
}

Shouldn't cout be in namespace std? Thus it should be std::cout or

Code: Select all

using namespace std;

somewhere before. And don't forget to flush your output stream, e.g. by appending <<std::endl; to really get the output at the place where you want to have it.
