I am having errors compiling a simple Hello World with g++ in linux.

The program source is written like this

1: #include <iostream.h>
2:
3: int main()
4: {
5: cout << "Hello World!\n";
6: return 0;
7: }

When I compile I get this error:

geoff@Geoffs-Ubuntu-X64:g++ Hello-World.cpp
Hello-World.cpp:1: error: stray ‘#’ in program
Hello-World.cpp:1: error: expected unqualified-id before numeric constant


I wrote the program exactly as told.

Ok I got the first exercise to work by removing the numbers. Now I got another problem compiling this source.

Source Code:

#include <iostream.h>
int main()
{
int x = 5;
int y = 7;
cout "\n";
cout << x + y << " " << x * y;
cout "\n";
return }

Error:

geoff@Geoffs-Ubuntu-X64:~/Documents/Learn-C++/Source/Learn-C++-in-21-Days$ g++ -Wno-deprecated Guess.cpp
Guess.cpp: In function ‘int main()’:
Guess.cpp:6: error: expected `;' before string constant
Guess.cpp:8: error: expected `;' before string constant

I have no idea what the program is supposed to do. The idea of the exercise is to take a guess at it.

Try
cout << "\n";
or
cout << endl;
instad of
cout "\n";

when using cout always use the << operator when adding elements to the stream.

 #include <iostream.h>
 int main()
 {
 int x = 5;
 int y = 7;
 cout "\n";
 cout << x + y << " " << x * y;
 cout "\n";

 return 0; // forgot the 0;
 }

 #include <iostream.h> do not use .h with standart libraries . <iostream> is just fine.

I am got a little problem while compiling a program including the my c++ features. The code is meant to connect to a my c++ server and grab some data. I am sure the codding is correct then what can i do?
