  • 第13题:

    以下关系表达式中,其值为False的是A.XYZ<"XYz"B.VisualBasic="visualbasic"C.the<>"there"D.Inte

    以下关系表达式中,其值为False的是

    A.XYZ<"XYz"

    B.VisualBasic="visualbasic"

    C.the<>"there"

    D.Integer>"Int"


    正确答案:B
    解析:本题通过关系表达式对字符串进行比较。在VisualBasic中,字符串数据按其ASCII码值进行比较。在比较两个字符串时,首先比较两个字符串的第一个字符,其中ASCII码值较大的字符所在的字符串大。如果第1个字符相同,则比较第2个……依此类推。在本题的4个选项中,选项A、选项C、选项D的值均为True;选项B中的两个字符串基本相同,但第1个字符串的第1个字母是大写字母,而第2个字符串的第1个字母是小写字母,第1个字符串小于第2个字符串,即两个字符串不相等,因此"VisualBasic"="visualbasic"的值为假,即False。
