# Answer to Question #17809 in C++ for Asma

Question #17809
A positive number N is called as perfect if the sum of its divisors is equal to N. For example, 28 is called as perfect since the sum of its divisors 1, 2, 4, 7, and 14 is equal to 28.
1- Write a C++ program that reads any positive integer and checks whether the number is perfect or not.
2- Display all the numbers between 2 and 10000 that are called perfect.

#include <iostream>
using namespace std;
main()
{int n,s=1,i=2,k=-1;
cout<<"Enter N: ";
cin>>n;

while(i<n){
if(n%i==0)
s+=i;
i++;
}

if(s==n)
cout<<" Perfect\n";
else cout<<" not perfect\n";
system("pause");

& }

2)

#include <iostream>
using namespace std;
main()
{int n,s=1,i=2,k=-1;
cout<<" Perfect:\n";
for (n=1;n<10000;n++){

while(i<n){
if(n%i==0)
s+=i;
i++;
}

if(s==n)
cout<<n<<" ";
& i=2;
& s=1;&
}

cout<<"\n";
system("pause");
& }
