Arrays issue involving mean and median

[lexiegrace]

The user is supposed to be able to enter the student's grades, and have the program output the median and mean. For some reason mine won't run and I keep getting the error "error C3861: 'median': identifier not found" Can anyone help me fix this issue?


#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;

//function prototypes
void mean(int [], int num);
void meadian(int [], int num);
void sort(int[], int);

int _tmain(int argc, _TCHAR* argv[])
{
double numStudents = 0;
float total = 0;
//declare array
int grades[100] = { 0 };
int i;

cout << "Enter the number of students who have taken the exam: " << endl;
cin >> numStudents;

//store data in array
for (int i = 0; i < numStudents; i++)
{
cout << "Enter the student's grade ";
cout << i + 1 << ": ";
cin >> grades[i];
while (grades[i] < 0 || grades[i]>100)
{
cout << "Invalid input. Please enter a value between 0 and 100." << endl;
cout << "\nPlease reenter grade " << i + 1 << ": ";
cin >> grades[i];
}//end while
}//end for

sort(grades, i);

system("pause");
}

void mean(int grades_new[], int num)
{
//get total and calculate mean
float total=0;
for (int i = 0; i < num; i++)
{
total = +grades_new[i];
}
cout << "The mean of the grades is " << total / num << endl;

median(grades_new, num);

}

void median(int grades_new[], int num)
{
//calculate the median
if (num % 2 != 0)//the number is odd
{
int temp = ((num + 1) / 2) - 1;
cout << "The median of the grades is " << grades_new[temp] << endl;
}
else
{
cout << "The median of the grades is " << grades_new[(num / 2) - 1] << " and " << grades_new[num / 2] << endl;
}
}

void sort(int grades_new[], int num)
{
//arrange values
for (int x = 0; x < num; x++)
{
for (int y = 0; y < num - 1; y++)
{
if (grades_new[y]>grades_new[y + 1])
{
int temp = grades_new[y + 1];
grades_new[y + 1] = grades_new[y];
grades_new[y] = temp;
}
}
}
median(grades_new, num);
}

At first glance, the error is telling you that you've tried to access a function which is not defined. Your problem is that within main, you're calling "meadian" when your function is actually named "median." Just a simple spelling mistake really. ;P
