题目大意:输入一个数n,然后求出约数的和sum,在与这一个数n进行比较,如果sum>n,则输出ABUNDANT,如果sum=n,则输出PERFECT,否则,输出DEFICIENT!
注意1的结果是DEFICIENT,0的结果是END OF OUTPUT!
1 #include <iostream> 2 #include <cstdio> 3 using namespace std; 4 int main () 5 { 6 int n; 7 cout<<"PERFECTION OUTPUT"<<endl; 8 while(cin>>n) 9 { 10 if(n==0) 11 { 12 cout<<"END OF OUTPUT"<<endl; 13 break; 14 } 15 if(n==1) 16 { 17 printf("%5d DEFICIENT\n",n); 18 continue; 19 } 20 int sum=1; 21 for (int i=2; i<n; i++) 22 if (n%i==0) 23 sum+=i; 24 if(sum<n) printf("%5d DEFICIENT\n",n); 25 else if(sum==n) printf("%5d PERFECT\n",n); 26 else printf("%5d ABUNDANT\n",n); 27 } 28 return 0; 29 }
