以下函数实现随机生成17位数(包括字母和数字),仍有改进的空间,可根据具体要求适当修改 Dim targetstring '调用返回函数给变量.Function过程通过函数名返回一个值 targetstring = targetrandstring("ABCDEFGHJKLMNPRSTUVWXYZ0123456789")'msgbox "车架号="& targetstring Function targetrandstring( constring) ' C
Given a string, determine if it is a palindrome, considering only alphanumeric characters and ignoring cases. For example,"A man, a plan, a canal: Panama"is a palindrome."race a car"is not a palindrome. Note: Have you consider that the
