Hi Guys,
I was wondering if any of you could help me out.. I am supposed to modify this code to user-defined functions but it keeps giving me an error for the first function definition after int main() so it is not compiling.. can any of you help me figure this problem out? I know the function goes after int main() but it is just not working.. any help would be appreciated.. thanks

After the code:
int CountNegatives(int count)
{

Error For Line 79: a function definition is not allowed here before "{" token

Code:
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>

using namespace std;

//function prototypes
int CountNegatives();
double AverageNonNegatives();
int SumRange(int,int);

int main()
{
    ifstream inFile;
    int i, choice, num, sum, num1, num2, count;
    double average;

    do
    {
             cout << "1 - Count Negatives" << endl;
             cout << "2 - Average Non-negatives" << endl;
