c++ - g++ error: invalid preprocessing directive #INCLUDE -

i tried testing mingw under windows 7 simple hello world program , got following errors:

c:\code\helloworld.cpp:2:2: error: invalid preprocessing directive #include c:\code\helloworld.cpp:3:7: error: expected neested-name-specifier before 'namespace' c:\code\helloworld.cpp:3:17: error: expected ';' before 'std' c:\code\helloworld.cpp:3:17: error: 'std' not name type c:\code\helloworld.cpp: in function 'int main()': c:\code\helloworld.cpp:7:2: error: 'cout' not declared in scope 

my original code follows:

//hello, world #include <iostream> using namesapce std;  int main() {     cout << "hello, world!";     return 0; } 

it should lowercase. use #include.

also, it's using namespace std; (typo in namespace).
