     Narcissistic number is also known as pluperfect digital invariant (PPDI), narcissistic number , exponentiation number , Armstrong number or Armstrong number . Narcissistic number refers to one. n is a positive integer that is a multiple of 3. The third power of the number in each digit is equal to itself. Then this is a narcissus number, such as 153. It is a narcissus number because 1³+5³+3³=153 .
The narcissus number is named after a mathematician in the early 19th century who discovered this interesting sequence and described it as a "perfect flower" because the digits in the numbers looked like petals. Narcissus only exists in single digits, double digits, and triple digits.

Extension:

The narcissus number is a type of autoexponential number. The names and numbers of other autoexponential numbers are as follows:

self-exponentiation	one person	three persons	four	five	Six	seven	eight bits	Nine	tenth place
name	Number of single people	Number of daffodils	four leaf rose number	Number of five-pointed stars	six combined numbers	Big Dipper Number	Eight Immortals	Number of Double Ninth Festival	perfect number
quantity		153、370、371、403	1634、8208、9474	54748、92727、93084	548834	1741725，4210818，9800817，9926315	1741725，4210818，9800817，9926315	1741725，4210818，9800817，9926315	1741725，4210818，9800817，9926315

Daffodil number example:

 int hundrd = 0;//定义一个整型变量 hundrd，并初始化为 0
 int ten = 0;//···
 int individul = 0;//···

 for (int i = 100; i <= 999; i++)//使用for循环遍历100-999之间的整数
 {
     hundrd = i / 100;//获取百位数字
     ten = i % 100 / 10;//获取十位数字
     individul = i % 100 % 10;//获取个位数字
     if (hundrd * hundrd * hundrd + ten * ten * ten + individul * individul * individul == i)//如果当前整数i是水仙花数，则满足以下等式:百位数的立方+十位数的立方+个位数立方等于当前整数i
     {
         Console.WriteLine(i+"是一个水仙花数");//输出i到控制台
     }
 }
 Console.ReadKey ();//等待用户按下任意键

Summarize:

To realize the narcissus number between 100-999 through C#, the core code is to obtain the hundreds, tens and digits by taking the cosine operation %, and then calculate their cubic sum. If the result of the cubic sum is equal to the integer itself, Then the integer is a narcissus number, and the result is finally output on the console.
