- backtick escapes
`like _so_` - quote by placing > at start of line

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

What is the sense to enter a string and it can not longer be used?choice == 2inside theswitchstatement: calling functions, pushingstrtovectors, etc. If you need to accessstrstrictly after the switch statement, it's a smell: there are no guarantees thatstrwill have a reasonable value after theswitchin general.
