problem with string.find()

[andriac]

i wrote a code to check the number of distinct char in a string whether even or odd using string.find(), but it seems it's not working !!!

#include <iostream>
#include<string>
using namespace std;

int main()
{   int x=0,z;
    string word;
    cin >> word;
    for(int j=0;j<word.size();j++)
        for(int i=j+1;i<word.size();i++)
        if(word.find(word[j],i)!=string::npos) 
         x++;

          z=word.size()-x;
    if (z%2==0) cout << "even";
  else cout << "odd";

    return 0;
}

Please explain "not working".

I don't think that your code does exactly what you intend.

What should be the result with input "aaaa"?

Could you use std::map?
