code: public static final int indexOf(char toBeFound, char[] array, int start)
  	{
  		for (int i = start; i < array.length; i++)

docs: Answers the first index in the array for which the corresponding character is equal to toBeFound starting the
  search at index start. Answers -1 if no occurrence of this character is found. <br>

  For example:
  <ol>
  <li>
  
  <pre>
  toBeFound = 'c'
  array = { ' a', 'b', 'c', 'd' }
  start = 2
  result =&gt; 2
  </pre>
  
  </li>
  <li>
  
  <pre>
  toBeFound = 'c'
  array = { ' a', 'b', 'c', 'd' }
  start = 3
  result =&gt; -1
  </pre>
  
  </li>
  <li>
  
  <pre>
  toBeFound = 'e'
  array = { ' a', 'b', 'c', 'd' }
  start = 1
  result =&gt; -1
  </pre>
  
  </li>
  </ol>
