How To Calculate the Average Smallest and the Largest Number in Array

This is the basic level programming exercise for beginners. The program calculates the Average Smallest and the Largest Number in a Given Array.

Source Code

#include<iostream>
using namespace std;
float division(float[],int);
float minMax(float[] ,int );
int main()
{
      int size;              //Array size
      cout << "How many numbers do you want to input? ";
      cin >> size;        
      float dataArray[size];     //Declaring dataArray        
   for(int index=0;index<size;index++)   //Loop which inputs arrays data 
                                
      {
              cout << "Number " << index+1 << " is: ";
              cin>>dataArray[index];
      }
      //Now calling division function to find the sum...
      cout<<"Average of dataArray elements is "<<division(dataArray,size)<< endl;
      minMax(dataArray,size);
      system("pause");
      return 0;
}
float division(float dataArray[],int size)
{
    float sum;
    float average=0;
    for(int index=0;index<size;index++)
        sum +=dataArray[index];
     average=sum/size;
     return average;
}
float minMax(float dataArray[],int size)
{
 int max;
 int min;
 max=dataArray[0];
 min=dataArray[0];
 
 for (int index=0 ; index<size; index++)
 {
  if (dataArray[index] > max) 
  {
   max = dataArray[index];
  }
  if (dataArray[index] < min) 
  {
   min= dataArray[index];
  }
 }
 cout<<"\nBiggest number is : "<<max;
 cout<<"\nSmallest number is: "<<min<<endl;
}
