[数值计算] 批处理加法运算中遇到的无法执行

夜未央

@echo on

set /a a = 1
set /a b= 2
set /a t = 2
echo a=%a%
echo b=%b%
echo t=%t%

(for /l %%i in (1,1,%t%) do (

   echo %%i%
   set entry%%i% 
   entry%%i% = %a% + %b% +1
   echo entry%%i%
   echo %entry%%i%%
   pause
))
echo %entry1%
echo %entry2%
echo 1
pause

想要输出加法运算后的两个数值，但实际执行中

F:\>(
echo 1
set entry1
entry1ab +1
echo entry1
echo
pause
)
1

等号左右两边不要有空格
for循环内部使用控制变量%%i而不是%%i%

@echo off
setlocal enabledelayedexpansion
set a=1
set b=2
set t=2
echo a=%a%
echo b=%b%
echo t=%t%

for /l %%i in (1,1,%t%) do (
    echo %%i
    set entry%%i=0
    set /a entry%%i=a+b+1
    echo entry%%i
    echo !entry%%i!
    pause
)
echo %entry1%
echo %entry2%
pause
