the index variable gets created upon each entry into the fork/join_none block. That occurs before spawning any process within the fork/join_none. In case 1) the variable initialization also occurs before any process within the fork/join_none. The thing that you need to remember is...

In contrast, the local variable i is allocated new memory whenever we call the automatic task. After the memory has been allocated, it is then assigned the value of 1. When the task has finished running, the dynamically allocated memory is freed and the local variable no longer exists. ...

Hierarchical reference to automatic variable 'addr' is not legal. 默认情况下,除了可以使用类范围解析运算符(::)访问静态属性和静态方法,还可以访问 –Static properties –Static methods –Typedefs –Enumeration –Structures –Unions 另外,这个类范围解析运算符(::)的作用可以只需要在类中定义方法的模版,具体...
