Write a C++ program to find sum & average of 1- dimensional integer array.

Write a C++ program to find sum & average of 1- dimensional integer array. 

Program Code:

#include<iostream>

using namespace std;

int main()

{

int array[20];

int number;

int i, j, sum=0, average=0;

cout<<"Enter number of elements you want to insert in the array : ";

cin>>number;

cout<<endl;

for(i=0;i<number;i++)

{

cout<<"Element "<<i+1<<":";

cin>>array[i];

cout<<endl;

}

for(j=0;j<number;j++)

{

sum = sum + array[j];

}

cout<<"The sum of all array element is :"<<sum;

cout<<endl;

cout<<"The average of Array is :"<<sum/number;

return 0;

}

The program code is tested on www.jdoodle.com

Output:

Enter number of elements you want to insert in the array : 5

Element 1: 1

Element 2: 2

Element 3: 3

Element 4: 4

Element 5: 5

The sum of all array element is :15

The average of Array is :3
