C language | Output the number of daffodils

Example 54: C language programming outputs all the "daffodil numbers" between 100-1000. The so-called "daffodil number" refers to a 3-digit number whose cube sum is equal to the number itself.

Analysis: 153 is a number of daffodils, because 153=1 ³⁺⁵ 3+3^3, you can judge each digit by digit, and each digit should be considered when writing the code.

Source code demo:

#include<stdio.h>//头文件 
int main()//主函数 
{
    
    
  int i,j,k,narcissistic_Number;//定义整型变量 
  printf("水仙花数是：\n");//提示语句 
  //小林这里要测试的100~1000之间的水仙花数 
  for(narcissistic_Number=100;narcissistic_Number<1000;narcissistic_Number++)
  {
    
     
    i=narcissistic_Number/100;//百位数字 
    j=narcissistic_Number/10-i*10;//十位数字 
    k=narcissistic_Number%10;//各位数字 
    if(narcissistic_Number==i*i*i+j*j*j+k*k*k)//符合其各位数字立方和等于该数本身
    {
    
    
      printf("%d ",narcissistic_Number);//输出这个数 
    }
  } 
  printf("\n");//换行 
  return 0;//主函数返回值为0 
}

The compilation and running results are as follows:

水仙花数是：
153 370 371 407
