Question

如果键入“c”的人应该在C ++中运行示例，我需要这样做，如果人类“j”应该运行Java示例。

可是：

1-当我输入“c”或“j”时无法识别，如果输入“j”，他会执行executeC，如果我选择“c”也会使executeC没有进入这个executeJava。然后改为数值，如果我输入3 - executeC，如果我输入4 - executeJava。因此，如果我键入3，它将访问目录C：\ Portico \ portico-1.0.2 \ examples \ cpp \ cpp13并处理executeC， 2-如果我输入4，它将访问目录C：\ Portico \ portico-1.0.2 \ examples \ java \ hla13，但不运行，只是结束。

查看我在命令提示符中执行的操作

C:\Portico\portico-1.0.2\exec>executePortico.bat main
Choose (J)ava or (C)++: 3
C:\Portico\portico-1.0.2\examples\cpp\cpp13\main.exe
Pressione qualquer tecla para continuar. . .

Terminated - Normal
C:\Portico\portico-1.0.2\exec>

请查看我的代码：

您似乎想要输入J或C进行分支，但是您正在测试3和4.它们都会失败并且代码会快速继续，因为没有其他逻辑处理错误的输入。试试这个细分：

if "%~0"=="" goto usage
if "%~1"=="" goto usage

set /p "language=Por favor escolha a linguagem (J)ava or (C)++: "

if /i "%language%"=="C" goto execC
if /i "%language%"=="J" goto execJ
echo incorrect input - quitting
goto :EOF

批处理 - IF语句
