(error LNK2019) problems

[llego1990]

Hello cplusplus community!
I'm currently working on this program for class and i think i have it all figured out except I keep on getting this linker error: error LNK2019. I searched throughout the forums, google and have seen similar problems but they are all particular to the program being compiled. Here is the source code for my program, also I am using visual studios 2010 as my compiler.

// This program serves as an exam grader.

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

const int SIZE = 25; //Size for arrays
const int LOCATION = 100; //Size for arrays


//Prototypes
void openAnswerKeyFile(ifstream & Answer1, char answerlocation);
void openStudentFile(ifstream & Answer2, char studentlocation1);
void openOutputFile(ofstream & output, char destination);
void readAnswerKey(ifstream & Answer, char answeraray1);
void readStudentFile(ifstream & student1, char stuAnswer1, char first1, char last1, char id1);
void checkExam(bool missed2, char stuanswer2, char answerKey2);
void writeResults(ofstream & destination3, bool missed3, char id3, char last3, char first3, int wrong3);
void writeMissedQuestionsList(ofstream & destination4, bool missed4, char stuAnswer4, char answerKey4);
void computeLetterGrade(int wrong5);

Any help will be very much appreciated!
Thanks!

Your declarations don't match the definitions

here is one...
declaration:
void writeMissedQuestionsList(ofstream & destination4, bool missed4, char stuAnswer4, char answerKey4);
Definition:

void writeResults(ofstream destination3, bool missed3[], char id3[], char last3[], char first3[],int &wrong3)
{
//...
}

You also have a lot of thing that are going to blow the bounds of arrays.
