Matching words between files

[chrisqo08]

I'm trying to write a program that reads text from one file and determines which words from that file were found and how many times they were found in another file. Then i need it to output this information to a separate file. My program is compiling but it crashes when I run it. I'm not sure whats wrong with it.

#include <iostream>
#include <string>
#include <fstream>

using namespace std;

int matchingwords(int count,int countnew,string A,string B);

int main()
{

ofstream fout("step2out.txt");

//intro
cout << "Welcome to MIDN Combado's project #2" << endl;

int count=0,countnew=0;
string words,A,B;

//open dictionary file
ifstream fin("EnglishDictionary.txt");

//count how many words are in file
while(!fin.eof()){

fin >> words;
count++;



//create array A and read strings from file
string *A= new string[count];

for(int i=0;i<count;i++) {
fin >> A[i];
}
}

fin.close();

//open file step2.txt
ifstream in("step2.txt");

//count how many words are in file step2.txt
while(!in.eof()) {
in >> words;
countnew++;


//create array B and read strings from file
string *B=new string[countnew];

for(int j=0;j<countnew;j++) {
in >> B[j];
}
}
in.close();
cout << matchingwords(count,countnew,A,B);
fout << matchingwords(count,countnew,A,B);


return 0;
}


int matchingwords(int count,int countnew, string A, string B)
{
int match=0;

for(int i=0;i<count;i++) {

for(int j=0;j<countnew;j++) {

if(A[i] == B[j]) {

match++;
}
}
}
return match;
}
