This question already has an answer here:
I've read up on several questions before finally deciding to post. This should be something trivial but I would like to know when it is most appropriate or if it is standard practice to end a how title with a question mark. Here's an illustration.
- Scenario one(what I think should be correct):
How to build a smart car.
- Scenario two:
How to build a smart car?
In my perhaps misguided interpretation, the second scenario makes it seem like whoever is posing the question would like to let us know how whatever action they're asking about can be done.
Say I need to ask a question on this forum, can I phrase my title like: "How to ask questions on this forum?" or "How to ask questions on this forum."?
TLDR: How do I use a question mark with a "How to do x" kind of title?
