Yes, but remember hello world examples are made for NEWBIES :). Teaching them a little won't hurt anyone.

When I was a C++ beginner, this main


--- Code: ---int main(int argc, char *argv[])

--- End code ---

always scared me :D.

Now a little less, but still... :D.

A typical new project at my work:
Fire up KDevelop.
New QMake project -> Hello world application
Nope Hello world is not for newbies, it's the beginning of everything ;)

when I do not need specific options

What is important is that the main must return type int.

Yes, you're right that only the int return type is important. However it's easier personally for me (and for the newbies) to delete the parameter list, than to re-type it (in case I need it). And for such console applications the command line parameters are frequently used...

What do you say about putting an "annoying" comment before the main... ? This way the newbies will not be scared, and this way they learn too...  :)

--- Code: ---// You may delete the parameter list, if you don't use it
int main(int argc, char *argv[])

--- End code ---

For advanced users - remember: you always have the option to make your own template... I think those predefined hello world templates should target the newcomers. But of course all this subject is a matter of personal taste.

Yes, that could be a useful addition. May be:


--- Code: ---// If you do not use the parameter list, you can use instead:
// int main()
int main(int argc, char *argv[])

--- End code ---

Important it is to not forget the returned type. I have read in an article that a teacher used:


--- Code: ---main()

--- End code ---

Because it was easier to understand for the students. There was not the problem of returned type... :roll:. Na ja, could be. But this is not C++ or not ISO standard C++.
