but local built-in variables are not. Beware that your compiler may default initialize local built-in variables, whereas an optimized build will not. Thus, code like the example above may appear to work, but it relies on undefined behavior. Assuming that you want initialization, an explicit de...
(Simple) Every constructor should initialize every member variable (either explicitly, via a delegating ctor call or via default construction). (简单)所有的构造函数都应该初始化每个成员(可以明确地通过委托构造函数或默认构造函数) (Simple) Default arguments to constructors suggest an in-class initializer ...
struct S { // Provide a default constructor by adding an empty function body. S() {} }; union { struct { S s; }; } u; Unions with anonymous structs In order to conform with the standard, the runtime behavior has changed for members of anonymous structures in unions. The constructo...

This option, and its inverse, let you make such a program work with the opposite default. The type "char" is always a distinct type from each of "signed char" or "unsigned char", even though its behavior is always just like one of those two. -fsigned-char Let the type "char" be ...
following this will actually lead to a non-deterministic behavior that will change if your class is or not a direct subclass of NSObject. Secondary Initializer As stated in the previous paragraph, a secondary initializer is a sort of convenience method to provide default values / behaviors to th...
This is the default behavior. Changing the javaWrapFunctions resource to "false" results in the behavior described in the following section. Controlling Listener Objects YourselfIf the javaWrapFunctions resource is set to "false", none of the callback object code described above is generated. In...
