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。

答案 0 :(得分:0)
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
