Help with functions

[mastajoda]

I'm writing a program for class that requires the use of arrays and functions to write a test with multiple choice. I have put together this code base on separate examples we had in class or from other sources. I have a problem with my fillResponArray function... I cant get the program to continue to the next question. It just works correctly with the first question and when I answer the question and hit enter, it scrolls down thru the questions about two times and never lets me answer any more... I'm not sure what is wrong here..

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

const int MAX = 20;
void OpenFile(ifstream & input, const string & message);
int fillQuesArray(string questions[], ifstream & inq);
int fillAnsrArray(int answers[], ifstream & inq);
void fillResponArray(const string questions[], int response[], int lenQ);
int GradedResponse(const int answers[], const int response[], int len);
void printQuesAnsResponses(const string questions[], const int answers[], const int response[], int len);

int main(){

cout<<"OKLAHOMA DEPARTMENT OF MOTOR VEHICLES\n";
cout<<"DRIVER'S LICENSE TEST\n";
ifstream in;
OpenFile(in, "questions");
string questions[MAX] = {};
int countQ = 0;
int lenQ = fillQuesArray(questions, in);
/*{
for (int i = 0; i < MAX; i++){
cout<<questions[i]<<endl;
}
system("Pause");
}*/
in.close();
ifstream inA;
OpenFile(inA, "answers");
/*{
for (int i = 0; i < MAX; i++){
cout<<questions[i]<<endl;
}
system("Pause");
}*/
in.close();

int answers[MAX];
int countA = 0;
int lenA = fillAnsrArray(answers, inA);

if(countQ != countA){
cout<<"Your questions do not match the answers you submitted.\n\n";
cout<<"The program will end now.\n\n";
system("Pause");
exit(0);
}


int response[MAX];
fillResponArray(questions, response, lenQ);
int score = 0;
score = GradedResponse(answers, response, lenQ);

Any help figuring this out would be greatly appreciated! I'm still a noob by the way, so I'll ask that you keep it simple! HA

Thanks
