  • 第1题：

    执行下列程序，显示的结果是______。

    first="china"

    second=""

    a=LEN(first)

    i=a

    DO WHILE i＞=1

    second=second+SUBSTR(first,i,1)

    i=i-1

    ENDDO

    ?second


    正确答案：anihc
    anihc 解析：变量a使用LEN函数取得字符串变量first的长度，该变量包含5个字母，所以它的长度为5，即a=5，然后将a的值赋给i，那么i也等于5。使用一个DO WHILE循环语句来操作，判断条件是变量i是否大于等于0，如果小于0，则退出循环，否则执行循环体。此时SUBSTR(first,5,1)的值为a，(从“china”字符串的第5位开始取一位字符)；执行i=i-1后，i=4，重复此循环体的操作，变量second的值依次为a、an、ani、anih，anihc，最后i0，退出循环体。
