数学趣题——寻找水仙花数

一个3位数若等于各位的立方和,即是水仙花数

源码如下:

   1: #include <stdio.h>
   2:  
   3: int IsNar(int a);
   4: void Nar();
   5:  
   6: int main()
   7: {
   8:     Nar();
   9:     return 0;
  10: }
  11:  
  12: void Nar()
  13: {
  14:     int i;
  15:     for (i=100; i<999; i++)
  16:     {
  17:         if (IsNar(i))
  18:         {
  19:             printf("%d ", i);
  20:         }
  21:     }
  22: }
  23:  
  24: int IsNar(int a)
  25: {
  26:     int sum = 0, tmp;
  27:     tmp = a;
  28:     while (tmp > 0)
  29:     {
  30:         sum += (tmp % 10) * (tmp %10) * (tmp %10);
  31:         tmp /= 10;
  32:     }
  33:  
  34:     if (sum == a)
  35:         return 1;
  36:     else
  37:         return 0;
  38: }
