有人可以帮我处理这个批处理脚本吗？ （设置/ p错误）

Question

所以我正在批量做一点“猜猜游戏”。 （你必须猜测1-20的数字）

这是代码的一部分：

    cls
    set /a guessnum = %random% %%20 +1 //Generates Number from 1-20
    echo A Number Between 1 - 20
    set /p "guess"=">>>Guess!" 
    *<----- The Code Crashes Right Here*
    if %guess% gtr %guessnum% echo The Number is smaller 
    if %guess% lss %guessnum% echo The Number is bigger
    if %guess% == %guessnum% goto righteasy

有人可以帮助我吗？

Answer 1

批量//Generates Number from 1-20中的结尾注释无效 请改用&rem Generates Number from 1-20。

set /a guessnum = %random% %%20 +1 //Generates Number from 1-20

为两个分裂标志返回missing operand error 因此guessnum未被定义，并且通过不正确的引用，输入变量被命名为guess"而不是guess

if %guess% gtr %guessnum% echo The Number is smaller

评估为：

if gtr echo The Number is smaller

返回

echo was unexpected at this time.

这批：

@echo off
cls
set cnt=0
set /a guessnum=%random% %%20 +1 &rem Generates Number from 1-20
echo A Number Between 1 - 20
:loop
set /p "guess=>>>Guess!"
set /a cnt+=1
rem *<----- The Code Crashes Right Here*
if %guess% gtr %guessnum% echo The Number is smaller&goto :loop
if %guess% lss %guessnum% echo The Number is bigger&goto :loop
Echo You got it right with %cnt% guess(es)

将生成此示例输出：

A Number Between 1 - 20
>>>Guess!10
The Number is smaller
>>>Guess!5
The Number is smaller
>>>Guess!3
You got it right with 3 guess(es)
