PLEASE USE VECTORS TO SOLVE. 

I will upvote if correct. 

#include <iostream>
#include <fstream>
#include <istream>
#include <string>
#include <vector>
using namespace std;
// Max matches that can be found
const int MAXDICTWORDS = 30000; // Max words that can be read in
const int MAXRESULTS = 20;
int loadDictionary(istream& dictfile, vector<string>& dict)
/*Places each string in dictfile into the vector
dict. Returns the number of words loaded into dict.*/
{
return -1; // This compiles, but this is incorrect
}
int permute(string word, vector<string>& dict, vector<string>& results)
/* Places all the permutations of word,
which are found in dict into results. Returns
thenumber of matched words found.*/
{
return -1; // This compiles, but this is incorrect
}
void display(vector<string>& results)
/* Displays size number of strings from results.
The results can be printed in any
order.*/
