body: <p>How to Reverse Find pointer to nth occurrence of a character in cstring/BSTR?</p>
  
  <pre><code>char * RFindNthOccurrence(char* src, char t, int n)
  {
     //for i/p string src = "HI,There,you,All"
     // and t =','
     // n =2
     //returned pointer should be at ",you,All" in same unchanged string
  }
  </code></pre>
  
  <p>I've found first and last occurrence searching, but without modifying string reverse finding nth occurrence is problem.</p>
