When posting code, please use code tags. Go Advanced, select the formatted code and click '#'.

main()

main() has a return value of type int so this should be

int main()

Beside what 2kaud already answered: each time you get a warning or error and the description is not enough clear, you can take a look in MSDN documentation for more details and examples.
Here is about Compiler Warning C4430.
