As C++ doesn't have Java Equivalent StringTokenizer class, I have implemented the class for my own and helps the beginners

This class helps the user to tokenize the Long string by specifying delimiter. I thought this will be helpful to the programmers who are at beginning stage.

Code Listing

// Constructor that takes 2 arguments 
// first argument is of string type that to be tokenized. 
// second argument is of string type that is used as token separator 
// and default separator is space 
StringTokenizer::StringTokenizer(CString str,CString sep=" ") 
    CString str1=""; 
    for (int i=0;i<str.GetLength() && sep.GetLength()==1;i++) 
    count=elements.GetSize (); 
// Method is used to fetch the tokens. 
CString StringTokenizer::getNextElement() 
        throw CString("Index out of Bounds"); 
    return elements.GetAt(index-1); 
//method used to fetch the count of tokens from the string 
int StringTokenizer::countElements() 
    return count; 

//fetch the elements at given position 
CString StringTokenizer::elementAt(int index) 
    if(index>=count ||index<0) 
        throw CString("Index out of Bounds"); 
        return elements.GetAt(index);
