答：=CHAR(RANDBETWEEN(65,70)) A~F

答：随机生成字母一般有2中方式 1. String chars = "abcdefghijklmnopqrstuvwxyz"; System.out.println(chars.charAt((int)(Math.random() * 26))); 根据chars 随机截取其中的一个字母. 2. char c=(char)(int)(Math.random()*26+97); System.out.pri...

答：=CHAR(INT(RAND()*26+65))&TEXT(RAND()*100000000000,"00000000000")

答：就是利用特定算法产生一组随机的字符，可以拿这串字符当代码，就能够保证密码拥有足够高的强度而不会像以生日做密码那样被黑客轻松地破解。

答：string[] s1 = { "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "...

答：密码安全策略和相关的安全标准都对密码的复杂度和长度有限制，安全管理人员也会教育用户使用多种字符组合出来的复杂的密码，还会建议用户对不同的系统使用不同的密码。 通常，要人们记住一两个复杂的密码并不太难，难得是记住一堆不同的密码，特...

答：1、生成随机数字 (1)生成随机数比较简单，=rand()即可生成0-1之间的随机数； (2)如果要是整数，就用=int(rand())*10，表示0至9的整数，以此类推； (3)如果要生成a与b之间的随机实数，就用=rand()*(b-a)+a，如果是要整数就用=int(rand()*(b-a))+a...
