C语言 goto 语句正确用法 在C语言中,有一个神奇的语句,那就是goto语句,它可以实现代码的任意跳转,看上去很好用,但是实际上用的不多,因为使用它可能会导致代码的错乱,所以实际应用中你会发现使用goto语句的时候不多,最能在B站上系统学习C语言的时候,看到老师对goto语句的适用方法描述例子写的不错,所以分享给大家。

Thegotostatement transfers control to the location specified bylabel. Thegotostatement must be in the same function as thelabelit is referring, it may appear before or after the label. If transfer of control exits the scope of any automatic variables (e.g. by jumping backwards to a point be...

Using agotostatement to jump to a label earlier in the same function body creates an iteration. Avoid creating iterations by usinggotostatements. Use iteration statements defined by the core language because they are easier to understand and maintain than goto statements. ...
创建QT项目时只有.pro文件,没有生成.cpp和.h文件 问题如下所示:创建untitled6工程时只有untitled6.pro,没有Headers和Sources文件 问题原因:新建工程时没有选择合适的构建套件,在windoWs下常见的有MSVC2013和MinGS。可以通过如下操作查看安装QT时系统添加的是哪种套件:点击菜单栏“工具”->“选项”->“编译器” 上...

The labeled statement designated byidentifiermust be in the current function. Allidentifiernames are members of an internal namespace and therefore do not interfere with other identifiers. A statement label is meaningful only to agotostatement; otherwise, statement labels are ignored. Labels cannot be...
