1． 编写Application程序,找出所有水仙花数,水仙花数是三位数,它的各位数字的立方和等于这三个数本身,

] args){ for( int i=100; i<=999; i++) if( IsShuixian(i) ) Console。WriteLine(i); Console。ReadKey();}// 判断是否是水仙数static public bool IsShuixian(int n){ int sum = 0; int s=n; while (n > 0) { int k = n % 10; sum += k * k * k; n /= 10; } return s == sum;}
