void main()

{

    int n, i, sum=0;

    clrscr();

    printf("Enter any Number : ");

    scanf("%d", &n);

    for(i=1; i<=n/2; i++)

    {

        if(n%i==0)

            sum=sum+i;

    }

    if(n==sum)

        printf("Given Number is Perfect Number ");

    else 

        printf("Given Number is Not Perfect Number");
