    This program reads "words" from cin and prints how many times each occurs.
    // Word frequencies -- using map
    // Fred Swartz 2001-12-11

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

    int main() {
        map<string, int> freq; // map of words and their frequencies
        string word;          // input buffer for words.

        //--- Read words/tokens from input stream
        while (cin >> word) {

        //--- Write the count and the word.
        map<string, int>::const_iterator iter;
        for (iter=freq.begin(); iter != freq.end(); ++iter) {
            cout << iter->second << " " << iter->first << endl;
        return 0;
    }//end main

    1. Clean up the "words" to remove punctuation, ignore numbers, etc.
    2. Read input from a file.
    3. Read another file of words to ignore.
    4. Sort the list from the most frequent to the least frequent.
