C++ writing style

When writing code (in C++ particularly), where do you put your curly braces?

ex:
int main()
{

}

OR...

int main(){

}

which do you think is better? clearer? more professional?

if (CheckDubs) {
    Print("Dubz check em'");
} else {
    Print(FindNextDubs(" nice dubs bro."));
}
