错在哪里请指点

今天从网上下的VC6.0,装好后用一段代码去测试,结果出错了.
代码是:
#include<stdio.h>
{
printf("Hello World\n");
}

出错提示:
--------------------Configuration: hello - Win32 Debug--------------------
Compiling...
hello.c
G:\C\hello\hello.c(2) : error C2449: found '{' at file scope (missing function header?)
G:\C\hello\hello.c(4) : error C2059: syntax error : '}'
Error executing cl.exe.

hello.exe - 2 error(s), 0 warning(s)

这是怎么回事啊?是我哪儿没做好?请指点,万分感谢!
