title: C++: Read a word from standard input and find out its length?
body: <p>I want to read a word from standard input and then find out its length in C++. I am currently using:</p>
  
  <pre><code>char str[80];
  cout &lt;&lt; "Enter your word: " &lt;&lt; endl;
  scanf("%s", str);
  </code></pre>
