Welcome to snippetvault.com.
This site is a repository of useful code snippets that others might find useful.
Why?
  1. They work in too many languages and can't remember something simple.
  2. They want a central place to store their samples and what better place than online.
  3. They don't want to bother registering on some other website.
  4. They want to help fellow coders do simple things without scouring Google.
