Explanation:

#include <iostream> using namespace std; bool is_Perfect(long long int n) {     long long int sum = 1;     for (long long int i=2; i*i<=n; i++)     {         if (n%i==0)         {             if(i*i!=n)                 sum = sum + i + n/i;             else                 sum=sum+i;         }     }      if (sum == n && n != 1)           return true;         return false; } int main(){     int n, perfect[8], size = 0;     cout<<"Input the 8 numbers;\n";     for(int i = 0; i < 8; i++){         cin>>n;         if(is_Perfect(n)){             perfect[i] = n;             size++;         }     }     if(size == 0) cout<<"No perfect numbers found!";     else{         cout<<"Perfect numbers: ";         for(int i = 0; i < size; i++) cout<<perfect[i]<<" ";     }     return 0; }
