Visual Studio 2013 c++ function syntax error -

i'm using vs 2013, reason in c++ console application simple function declaration not work. going on?

i have #include iostream , code inside int main () {...} body.

-tsr

update:

look @ comment in program. should write functions outside of main method.

/* wrong code ----------------------------------------- */ #include <iostream>  int main() {  int printmessage ()  {  } }   /* correct code ---------------------------------------- */ #include <iostream>  int printmessage () { }  int main() {     }
