    while(i<=10)
    {
        printf("Enter number %d : ",i);
        scanf("%d",&n);
        if(n<0)
        {
            printf("enter only positive numbers\n");
            continue;
        }
        sum+=n;
        i++;
    }
    avg=sum/10.0;
    printf("sum=%d avg=%f\n",sum,avg);
    return 0;
