[問題] 找perfect number
開發平台： (例: VC++ or gcc/g++ or Dev-C++, Windows or Linux)
VC++
有問題的code： (請善用置底文標色功能)
#include "stdafx.h"
#include"iostream"//標頭檔
#include"iomanip"
#include"cmath"
using namespace std;
using std::setw;
using std::fixed;
using std::setprecision;
void PerfectNumber(unsigned long double num,unsigned long double &count);
int _tmain(int argc, _TCHAR* argv[])
{
unsigned long double a,i,j,k,co=0;
cin>>a;
for(i=2;i<=a;i++)
{
PerfectNumber(i,co);
}
cout<<"the total is "<<co<<endl;
system("pause");
return 0;
}
void PerfectNumber(unsigned long double num,unsigned long double &count)
{
unsigned long double i,j,sum=0;
//count=0;
if(num%2==0)
{
for(j=1;j<num-1;j++)
if(num%j==0)
{
sum=sum+j;
}
if(sum==num)
{
cout<<num<<" is a perfect number"<<endl;
count=count+1;
}
}
}
補充說明：
以編譯過但不知要怎找才能找到8589069059
就是可以讓他快一點嗎
以上CODE是過的
謝
