title: C password validation?
body: <p>I'm being bugged right now because I'm making a little password validation thing in C.</p>
  
  <p>the case is </p>
  
  <ol>
  <li>It should have at least 8 characters entered</li>
  <li>It should have at least 1 number</li>
  <li>It should have at least 1 uppercase / lowercase letter.</li>
  </ol>
  
  <p>For example:
  if the rules are not complied it would show</p>
  
  <p>Enter your password: doratheexplorer</p>
  
  <pre><code>NOT A GOOD PASSWORD 
  NO DIGIT
  NO UPPERCASE LETTER
  </code></pre>
  
  <p>else 
  continue</p>
  
  <p>how would I do something like this? do I need to use string.h?</p>
