嗨,我現在做簡單的批處理文件,我試圖在最後添加正確的答案編號,但它一直說零,因爲當選擇答案時變量值不會改變。這裏是我的代碼如下如何設置變量值如果
@echo off
title Game One
color 1f
::#############################
:one
set correctn=0
set correctn2=0
cls
echo What is 2 + 2?
echo.
echo.
echo A) 6
echo B) 4
echo C) 49
echo D) 17
echo.

echo Type the correct answer.
set /p ch1=
echo.

if not defined ch1 (goto one)

那麼如果如果已經變量存在if語句如何更改變量值?
你缺少** *設置*關鍵字。 EG使用**如果%ch1%== A set correctn = 0 ** –
沒有抱歉,我試過了,但沒有奏效。但是我做了一些讓它工作的東西,問題是我的if,我改變它,以便它在下一頁之前設置值。但是你幫我弄清楚了這一套 –
