Question

学生档案文件包含每位学生的姓名，性别（M或F），年龄（年份）和婚姻状况（单身或已婚）。设计一种算法，读取文件并计算已婚男性，单身男性和已婚女性的数量。在学生摘要报告中打印这些数字。如果任何单身男性超过30岁。在单独的符合条件的单身汉报告上打印他们的姓名和年龄。

任何人都可以告诉我，我的错在任何一行吗？谢谢！希望你能帮助我！

Answer 1

在下面的代码中，我完成了以下操作：

添加了boolean，以防止您为每一行打印Eligible bachelors Report标题。
缩进代码以便于阅读。
将您‘的使用替换为'，因为您显然使用了诸如MS-Word之类的文字处理程序来编写代码。（我可以建议NotePad++吗？）

我完全保留了您的代码：我认为ElseIf不是您伪代码中的有效关键字，而您的教授可能会传递一个包含M以外的性别的文件F。

Set marriedMen to 0
Set singleMen to 0
Set marriedWomen to 0
Set singleWomen to 0 
Set hasPrintedHeader to False

READ name, sex, age, status
DOWHILE(NOT EOF)
    IF (status = married) THEN  //check if status is married, if yes then check next
        IF (sex = 'F') THEN     //check if sex is F, if yes then +1
            marriedWomen = marriedWomen + 1
        ELSE
            IF (sex = 'M') THEN     //under married, and sex is M then +1
                marriedMen = marriedMen + 1
            ENDIF
        ENDIF
    ENDIF

    IF (status = single) THEN   //check if status is single, if yes then check next
        IF (sex = 'F') THEN     //check if sex is F, if yes then +1 to singleWomen
            singleWomen = singleWomen + 1
        ELSE
            IF (sex = 'M') THEN     //under single, and sex is M then +1
                singleMen = singleMen + 1
                IF (age > 30) THEN      //under single, sex = M and age is over 30 then print the name, age
                    IF (hasPrintedHeader = False) THEN
                        Print 'Eligible bachelors Report'
                        hasPrintedHeader = True
                    END IF
                    Print 'Name: ', name
                    Print 'Age: ', age
                ENDIF
            ENDIF
        ENDIF 
    ENDIF
    READ next record
ENDDO

Print 'Student Summary Report'
Print 'Married Men: ', marriedMen
Print 'Single Men: ', singleMen
Print 'Married Women: ', marriedWomen
Print 'Single Women: ', singleWomen

Answer 2

DrawTree（n，方向，长度）

if n > 0 do

    DrawTrunk(direction, length)

    DrawTree(n-1, 3DRandomAngle(direction), length*Factor(n))

    DrawTree(n-1, direction + random % 10, length*Factor(n))

    DrawTree(n-1, 3DRandomAngle(direction), length*Factor(n))

else

    DrawLeaf()

end if

结束DrawTree
