If the base class function isn't declared asvirtual, then the derived class function is said tohideit. Both overriding and hiding are distinct from overloading. Block scope is strictly observed. A function declared in file scope isn't in the same scope as a function declared locally. If ...

Chapter 3: Function vs. Block Scope As we explored in Chapter 2, scope consists of a series of "bubbles" that each act as a container or bucket, in which identifiers (variables, functions) are declared. These bubbles nest neatly inside each other, and this nesting is defined at author-ti...
The parameters declared in the declarator of a function definition are in scope within the body. If a parameter is not used in the function body, it does not need to be named (it's sufficient to use an abstract declarator): void print(int a, int) // second parameter is not used { ...
像这样看。 当您尝试访问定义范围之外的局部变量时,您会收到“variable not declared in this scope”错误,如上面的示例所示。 但是,如果您尝试访问定义范围之外的局部变量的地址,则会出现function returns the address of the local variable的错误。 这就是发生这种情况的原因。
