赋值5-3伪码检查
提问于 2022-06-05 14:37:59
我已经完成了这个任务，但我只想有人检查一下，以确保它是正确的。以下说明：
创建伪代码或流程图，逻辑上勾勒出允许玩家在房间之间移动的步骤，使用命令向北、南、东和西移动。确保解决以下问题：
，
- ，你需要从玩家那里输入什么？您将如何提示播放机输入？您将如何验证输入？
，
- ，如果玩家进入一个有效的方向，程序应该做什么？输出结果是什么？
，
- ，如果玩家输入无效的方向，程序应该做什么？将产生什么输出？
- ，您将如何通过决策分支和循环控制程序流？
这是我的密码：
START
currentRm=’Foyer’
PRINT ‘You are in the Foyer
BEGIN LOOP
INPUT ‘Which direction do you want to go?’
IF currentRm IS ‘Foyer’
IF direction IS ‘East’
currentRm = ‘Kitchen’
OUTPUT ‘You are in the Kitchen’
ELSE
OUTPUT ‘Invalid Direction. Try again’
ELIF currentRm IS ‘Kitchen’
INPUT ‘Where do you want to go?’
IF direction IS ‘North’
currentRm = ‘Living Room’
OUTPUT’You are in the Living Room’
ELIF direction IS ‘South’
currentRm = ‘Dining Room’
OUTPUT’You are in the Dining Room’
ELIF direction IS ‘East’
currentRm = ‘Bedroom’
OUTPUT ‘You are in the Bedroom’
ELIF direction IS ‘West’
currentRm = ‘Foyer’
OUTPUT ‘You are in the Foyer’
ELSE
OUTPUT ‘Invalid Direction. Try again’
ELIF currentRM IS ‘Living Room’
INPUT ‘Where do you want to go?’
IF direction IS ‘East’
currentRm = ‘Gaming Room’
PRINT ‘You are in the Gaming Room’
ELIF direction IS ‘South’
currentRm = ‘Kitchen’

几点意见：
- 当当前房间不是“休息室”时，代码会问两个问题：
“你想往哪个方向走？”“你想去哪里？”
这是不对的。第一个问题是不管你住在哪个房间，也不应该问特定房间的第二个问题。因此，从所有这些INPUT块中删除该ELIF语句.
- 循环永远不会结束，而且由于指令中没有指示循环应该结束，这是很好的。但这也意味着程序中的最后两个语句永远不会执行：
如果currentRm =“游戏室”输出“游戏结束”
如果打算在用户进入游戏厅时显示该输出，并且程序可能应该结束，则需要在循环中移动这段代码，在该循环中，您已经检测到用户进入了该房间：
如果方向是‘东方’currentRm =‘游戏室’打印‘你是在游戏室’输出‘游戏超过’退出循环‘
- ，您可以避免代码重复，并通过
PRINT ‘You are in the ’, currentRm组合PRINT ‘You are in the Kitchen’的所有变体，并将该语句移动到对所有情况都执行该语句的位置。
在实际编程语言中，
- 将创建一个图形数据结构，并避免使用这些
IF..ELIF块。该数据结构的外观将取决于编程语言.
- 您应该稍微改进代码的缩进。确保在
IF或ELIF语句之后代码更缩进(4个空格是一个很好的标准)，并且作为该块一部分的所有语句都在相同的缩进级别上。
