expected constructor, destructor, or type conversion before ‘(’ token|

 1 #include 
 2 #include 
 3 using namespace std;
 4 
 5 int f()
 6 {
 7     cout<<"hello world"<<endl;
 8     return 4;
 9 };
10 //cout<<"hello world"<
11 printf("hello world\n");
12 int s = f();
13 
14 int main()
15 {
16     return 0;
17 }

11行错误！
