I"m having trouble with this code can any help? I am trying to find the average, mean, standard deviation

```
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
using namespace std;
void Fill_Array(int Size[], int& count);
void Print_Array(int Size[], int count);
double Calc_Average(int Size[], double average);
void Sort(int Size[], int numbers_used);
int Calc_Median(int median, const int Size[]);
int Calc_Standard_Deviation;
int Variance;
void Print_Array_and_Calculations(int median, double average, int standard_deviation,int Variance);
int main()
{
int count;
int Size [11],
numbers_used = 0,
median = 0;
double average = 0;
double standard_deviation;
double variance;
Fill_Array(Size, count);
Print_Array(Size, count);
average = Calc_Average(Size, average);
Sort(Size, numbers_used);
Calc_Median(median, Size);
Print_Array_and_Calculations(median, average, standard_deviation, variance);
return 0;
}
void Fill_Array(int Size[], int& count, int& number_used)
{
ifstream in_size;
string text_file;
cout << "Enter the file to read in:";
getline(cin, text_file);
cout << endl << "The numbers in the array are:" << endl << endl;
if(in_size.fail())
{
cerr << "Error opening file";
exit(1);
}
void Print_Array(int Size[], int count)
number_used = 0;
for(int index = 0; index < number_used; index++)
cout << Size[index] << " ";
}
double Calc_Average(int Size[], double average)
{
int total = 0;
for (int i = 0; i < 11; i++)
{
total = total + Size[i];
}
average = double(total) / 11;
{
return average;
}
void Sort(int Size[], int number_used)
{
for (int index = 0; index < number_used - 1; index++)
{
Variance= sum/(n-1);
return variance;
}
int Calc_Median(int median, int Size[])
{
median = Size [ Size/ 11 ];
return median;
}
int Cal_Standard_Deviation(int Cal_Standard_Deviation, int
void Print_Array_and_Calculations(int median, double average,int standard deviation, int variance);
{
cout << "The average of the numbers is " << average;
cout << "The median of the numbers is " << median;
cout << "The standard deviation is " << deviation;
cout << "The Variance is "<<sqrt(variance)<< endl;
}
```
