Answer:
Following are the program to the given question:
#include <iostream>//header file
#include <bits/stdc++.h>//header file
using namespace std;
int main()//main method
{
int x,i,sum=0;//defining integer variable
double average, median;//defining double variable
cout<<"How many students were surveyed? ";//print message
cin>>x;//input value
int *a = new int[x]; //dynamically created array
for(i = 0;i<x;i++)//defining for loop to input value in array
{
cout<<"Enter the number of movies seen by student number "<<i+1<<": ";//print message
cin>>a[i];//input value
}
for (int i = 0; i < x; i++)//defining loop for add value
sum += a[i]; //use sum to add array value
average = (double)sum/x;//defining average variable to calculate average
cout<<"Average is "<<average<<endl;//print average value with message
sort(a, a+x); //use sort method to sort array to find the median
if (x % 2 != 0)//use if to check the even value
median = (double)a[x/2];//calculating the median value
else//esle block
median = (double)(a[(x-1)/2] + a[x/2])/2.0;//calculating median value
cout<<"Median is "<<median<<endl;//print median value with message
int m_count=1 ,mode= a[0], c_count = 0;//defining integer variable
for( i=1;i<x;i++)//defining for loop arrenge value
{
if(a[i]==a[i-1])//use if to check array value
{
c_count++;//increment c_count variable value
}
else//else block
{
if(c_count>m_count)//use if to check c_count greater than m_count
{
m_count = c_count;//holding value in m_count
mode = a[i-1];//holding mode value
}
c_count = 1;//holding value integer value in c_count
}
}
cout<<"Mode is "<<mode;//print mode value with message
return 0;
}

Explanation:
- Including header file.
- Defining the main method.
- Declaring integer and double type variables.
- Declaring integer array.
- Use the loop to the input value.
- After input, the value uses double variable "average, the median" that uses the for loop and conditional statement to check the value and hold in its variable.
- In the next step, another integer variable "m_count, mode, and c_count" is defined that uses the loop and conditional statement to check the median and mode value and hold its value into their variable.
