URI Problem : 1164

Solution :

	#include<stdio.h>
	int perfect_number(int n);
	int main()
	{
	int n,i,test;
	while(scanf("%d",&test)==1){
	for(i=1;i<=test;i++){
	scanf("%d",&n);
	if(n==perfect_number(n)){
	printf("%d eh perfeito\n",n);
	}
	else
	printf("%d nao eh perfeito\n",n);
	}
	}
	return 0;
	}
	int perfect_number(int n)
	{
	int i=1,per_num=0;
	while(i<n){
	if(n%i==0)
	per_num=per_num+i;
	i++;
	}
	if(per_num==n)
	return n;
	}
