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。

Use exceptions andRAII使用例外和RAII for non-RAII resources, use finally. 对于非RAII资源,使用finally处理。 原文链接 https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#nr6-dont-place-all-cleanup-actions-at-the-end-of-a-function-and-goto-exit...
Usually, these label identifiers are available everywhere in the scope of the function. So, they can be referred to by goto statements that are located before the label. The previous scope rule is different from the one for variables - that forces the variables to be declared before they are...

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...
