    做题思路:先分离位数,再求数值,最后匹配

    #include <bits/stdc++.h>
     using namespace std;
     int main(){
       int a,ge,shi,bai;
       cin >> a;
       ge = a % 10;
       shi = a % 100 / 10;
      	bai = a / 100;
       int pow_ans = pow(ge,3) + pow(shi,3) + pow(bai,3);
      	if( pow_ans == a){
      		cout << "YES";
      	}
      	else{
         cout << "NO";
      	}
      	return 0;
      }

      实际上就是一道比较简单的一道题 也是一道初学者学习C++的经典例题

      想要代码的先看这里

      #include <bits/stdc++.h>
      using namespace std;
      int a,b,c,n;
      int main()
      {
      	cin >> n;
      	int m = n;
      	c = n % 10;
      	n /= 10;
      	b = n % 10;
      	n /= 10;
      	a = n;
      	if(a*a*a+b*b*b+c*c*c==m)
      	{
      		cout << "YES";
      	}
      	else
      	{
      		cout << "NO";
      	}
      	return 0;
      }
      

      不过我还是不建议你这样做,毕竟复制粘贴谁都会是吧

      你可以看看这个注释版,理解一下这个代码

      #include <bits/stdc++.h> 
      //万能头文件,如果你是初学者的话直接抄很容易被老师发现 
      //建议改成  #include <iostream> 
      using namespace std;//命名空间 
      int a,b,c,n;//题目的输入是一个三位数,我们分别用a,b,c储存这个数的个十百位数
      //n则用来储存输入的数 
      int main()
      {
      	cin >> n;//首先,我们要先输入这个数 
      	int m=n;//因为这个n要用来运算,为了后面的比较,我们要先储存n 
      	c = n%10;//c是n的个位数,这个“%”是取余,所以这里的c就是n除以10的余数 
      	n /= 10;//意思是n变成n除以10的商 
      	b = n%10;//同上 
      	n /= 10; 
      	a = n;//最后a=n; 
      	if(a*a*a+b*b*b+c*c*c==m)//判断水仙花数(根据题意) 
      	{
      		cout << "YES";//是的话输出YES 
      	}
      	else
      	{
      		cout << "NO";//不是就输出NO 
      	}
      	return 0;
      }
      
      

      注意!! 1、输出的字母全是大写,不然0分! 2、不要把%和/弄混了! 3、是三次方,要乘3次!

      好了,就这样

                本题思路:分别将每个数提取出,并进行判断。
                计算乘方的快捷方式:

                pow(double x, double y);
                

                返回值:x的y次方
                注意:此函数需要包括库:

                #include <cmath>

                    int one=n-hund*100-ten*10;
                    if(pow(hund,3)+pow(ten,3)+pow(one,3)==n) cout<<"YES";
                    else cout<<"NO";
