C++ Program of Sum, Multiplication, Average Program in Array

In this program we will learn how to calculate sum, multiply and average of numbers stored in array.

The code is given below.

//Code Starts

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

  int n,a[n],sum=0,mul=1;

  float avg;

 

  cout<<"Enter Size of Array : ";

  cin>>n;

 

  for(int i=0;i<n;i++)

  {

    cout<<"Enter Number at "<<i<<" index : ";

    cin>>a[i];

  

    sum=sum+a[i];

    mul=mul*a[i];

  }

 cout<<"Sum = "<<sum<<endl;

 cout<<"Multiplication = "<<mul<<endl;

 avg=sum/n;

 cout<<"Average = "<<avg;

 getch();

}

//Code Ends
