    scanf("%d", &num);
    // Calculate sum of all proper divisors
    for(i = 1; i <= num / 2; i++)
    {
        //if i is a proper divisor of num
        if(num%i == 0)
        {
            sum += i;
        }
    }
    // Check whether the sum of proper
    //divisors is equal to num or not
    if(sum == num)
    {
        printf("%d is perfect number", num);
    }
    else
