You are trying to compile CLI/C++ code in C++ compiler.
CLI/C++ is different language from C++, althrough it looks similar to it.
Also you have missed commas in function call
Try:

#include <iostream>
#include <windows.h>
using namespace std;

int main ( int argc, char* argv[])
{
    MessageBox(NULL, "hello world \nThis is the 2nd line.", "hello", MB_OKYESCANCEL);
    cin.get();
}
