Hi,

you can do it in a cleaner way using STL map and getting rid
of all the messy strtok() functions. Just writing how to
construct the map. The idea of putting into a vector and
sorting can still work.

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

int main(int argc,char*argv[])
{
string word;
map <string, int> freq;
map <string, int>::const_iterator wordsit;
fstream myfile;
myfile.open(argv[1],ios::in);

// Load file into string
if (myfile.is_open())
{
while (myfile >> word)
{ freq[word]++;
}
myfile.close();
}

//To see the map created
for (wordsit=freq.begin();wordsit!=freq.end();wordsit++)
{cout<<"Key: "<<wordsit->first<<"Value:
"<<wordsit->second<<endl;
}
