Asp.net (c #) daffodils

The number of daffodils: A three-digit integer. the cube and the number equal to the number itself are called the number of daffodils. There are four daffodils: 153, 370, 371, 407 (for example, 1 ^ 3 + 5 ^ 3 + 3 ^ 3 = 153 ). The code I wrote is as follows. you can comment on other implementation codes.

Int I, m, n, k;
For (I = 100; I <1000; I ++)
{
// Obtain hundreds of BITs
M = I/100;
// Obtain ten digits. n = (I % 100)/10 can be used here;
N = I/10% 10;
// Obtain the single digit
K = I % 10;
// Print the number of daffodils
If (m * m + n * n + k * k = I)
Response. Write (I + "<br/> ");
}
