        cout<<"\n How Many Numbers You Want to Enter? \n";
        cin>>num;
        cout<<"\n Enter "<<num<<" Numbers : \n";
        for(i=0; i<num; i++)
        {
                cin>>arr[i];
                sum=sum+arr[i];
        }
        int armean=sum/num;
        cout<<"\n Arithmetic Mean = "<<armean;
        return 0;
}


Output:

arithmetic mean
