title: Comparing a word in a string
body: <p>What function should I use if I need to perform an action when a certain word is NOT found AT THE START of a string?
  Let's say I want to perform an action if the string does not start with "The".
  So if:</p>
  
  <pre><code>char *str = "This is a string";
  </code></pre>
  
  <p>the code will perform the action. But if:</p>
  
  <pre><code>char *str = "The quick brown fox jumps over the lazy dog.";
  </code></pre>
  
  <p>the action will not happen.</p>
  
  <p>NOTE: Case of the letters matter. The word to be compared in the string may not be separated by a space.
  Also, if it would affect the code in anyway, what if I need to compare the string with 2 different words?</p>
