Tell It by Myself…
This is a typical Cprogramming question, it tells how to separate the 3 numbers: 它的中文名是：水仙花数

输出所有的“水仙花数”，所谓的“水仙花数”是指一个三位数其各位数字的立方和等于该数本身，例如153是“水仙花数”，因为：。
Do it by myself
#include <stdio.h>
int main(){
int i,j,k;
for (int n = 100;n<1000;n++){
i = n/100;
j = (n-i*100)/10
k = n%10;
if (n == i*i*i+j*j*j+k*k*k){
printf ("%d ",n);
}
}
return 0;
}
