Sounds like your code is not conformant with C++ (i.e. you're not writing C++ code).

One problem is using Dev-C++.

[maddave]

#include <iostream.h>

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

[Moschops]

That's not conformant with the C++ standard. There is no such header file as iostream.h in C++

Try this instead:

#include <iostream>

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

[maddave]

[Moschops]

You should have learned about it already. Whatever you're using to learn C++ from, stop. It's not teaching you C++.
