    double avg;
    cout<<"Enter the Element of the array:\n";
     for(j=1;j<=size;j++)
    {
        cin>>arr[j];
        if(j%2!=0){
            sum+=arr[j];
            cou++;
        }
    }

Code:

import java.util.Scanner;
public class p12 {

public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("Enter the size of the array:");
    int size;
    size=sc.nextInt();
    int arr[ ]=new int[size];
int j,sum=0,cout=0;
double avg;
System.out.println("Enter the Element of the array:");
       for(j=0;j<size;j++)
        {
        arr[j]=sc.nextInt(); 
        if((j+1)%2!=0){
            sum+=arr[j];
            cout++;
        }
    }
     avg=(double)sum/(double)cout;
     System.out.println("Average of Numbers in array at Odd position is "+avg);
     sc.close();
}
}

Program in Python

Here is the source code of the Python Program to Print Average of Numbers in array at Odd position.

Code:

arr=[]
cout=0
sum=0
size = int(input("Enter the size of the array: "))
print("Enter the Element of the array:")
for i in range(0,size):
    num = int(input())
    arr.append(num)
for j in range(0, size):
