#include<iostream>
using namespace std;
int divizori (int n)
{
int i;
for(i=1;i<=n;i++)
if(n%i==0)
cout<<i<<" ";
}
int main ()
{
int n;
cout<<"numarul este ";
cin>>n;
divizori(n);
return 0;
}

else
return false;
}
int main()
{
double n;
cout<<"numarul este ";
cin>>n;
cout<<patrat_perfect(n);
return 0;
}
