am not sure about how to use the struct which you have already mentioned ?

struct s
{
    string strWord;
    int nCount;
};
 
vector<s> vec;

Before each call to push_back(), check first to see if the word already exists.

struct s
{
public:
    s(){}
    string strWord;
    int nCount;
 
    bool operator==(const s& b)
    {
        return strWord == b.strWord;
    }

s s4;
s4.strWord = "word to search for";
 
vector<s>::iterator it = find(vec.begin(), vec.end(), s4);
if (it != vec.end())
{
    // found it

	{

		i = find_if(i+1, e, bind2nd(not_equal_to<string>(), *i));
	}
}

NiceNaiduhe problem is i have never worked on STL collections before.

<br />
CMyElement* CMyArray::operator[]( int iIndex )<br />
{<br />
//...<br />
}<br />
