#include  using namespace std; int main() { int *studentnum; int students_surveyed; int count; int total; double average; double median; cout<<"How many student are surveyed?"<< endl; cin>> students_surveyed; studentnum = new int [students_surveyed]; cout<<"Write by order, the number of movies watched by each of the students" <> studentnum [count]; } total += studentnum [count]; average = total/students_surveyed; { cout<< "The total of movies watched by all the students is:" << total << "movie." < 
 
 
I need to build 3 functions, one that calculates and display the average of the movies watched, the median and the mode. Three different functions. I had the idea of using one of my functions but I don't know how to implement it as one of the requirements is: All array accessing should be done with pointers and not via direct access. For example, if I had an integer array called movies and wanted to access index. 
 
This is my function: 
 
double findAverage(double m[], int size) { int count = 0; double total = 0; for (int i = 0; ireturn total / count; } 
 
And also I need to do some input validation of the movies, I can't allow negative numbers.
