Utils.cpp function and getting prefilled array from text file - c

Question

This file needs to read a text file with numbers on each line, and preload the values from the text file into myArray. It also needs to read the integer for arraySize, so that it can be used to calculate the mean and median. The code is in c, but the teacher uses c++ file names and doesn't want us t change it. I also want to total the numbers, but when executed it doesn't print anything.
#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#include "Utils.cpp"
int main(void)
{
//declare variables
int myArray[]={};
// declare a string to hold the name of the file
// that will be read into your statsArray
char statsFile[] = "2005.txt"; /* file to be read in */
int arraySize = getFileSize(statsFile); /* determine size of file */
//dynamically declare statsArray based on size of file
int *statsArray = (int*)malloc(sizeof(int)*arraySize);
// initialize arrays with zero values
initializeArray(myArray, arraySize);
//load array from file
loadArray(myArray, arraySize, statsFile);
// sum stats array
int total=0;
for(int x=0;x<myArray[arraySize-1];x++){
total+=myArray[x]; //adds each element of array to total
}
printf("%i",total);
Here is the utils.cpp that was provided.
#include <stdio.h>
int getFileSize(char fileName[])
{
FILE *fr; /* declare the file pointer */
int c; /*Nb int (not char) for the EOF */
int newlineCount = 0;
// open the file to count the lines
fr = fopen(fileName, "rt");
// count the newline characters
while ( (c=fgetc(fr)) != EOF)
{
if (c =='\n')
newlineCount++;
}
return newlineCount;
}
void loadArray(int list[], int size, char fileName[])
{
FILE *fr; // declare the file pointer
int count = 0; // running line count
char line[80];
fr = fopen(fileName, "rt");
while(fgets(line, 80, fr) != NULL)
{
// get a line, p to 80 chars fr. done if NULL
sscanf(line, "%i", &list[count]);
count++;
}
}
void initializeArray(int list[], int size)
{
for (int i = 0; i < size; i++)
{
list[i] = 0;
}
}
void sortArray(int list[], int size)
{
int tempNumber;
for (int i = 0; i < size; i++)
{
for (int j = i +1; j < size; j++)
{
if(list[i] > list[j])
{
tempNumber = list[i];
list[i] = list[j];
list[j] = tempNumber;
}
}
}
}
