Nothing wrong with that code, it compiles and runs fine.

Maybe some invisible characters in line 4. Copy the text into a simple editor (notepad or something similar) and save it again.

There's nothing wrong with that code.

Unless you're trying to compile C++ code using a compiler that only supports C, or you've used the wrong command line arguments for your compiler, whatever that is.
