The following initialization is no longer allowed: C++ Copy void *p = {{0}}; To correct this code, use either of these forms: C++ Copy void *p = 0; // or void *p = {0}; Name lookup has changed. The following code is resolved differently in the C++ compiler in Visual Studio...
These are just a couple of examples where it isn't strictly necessary to initialize a variable, since it's set later (but not accessed between declaration and initialization). In general though, it doesn't hurt to always initialize your variables at declaration (and indeed, this is probably ...
warning: type mismatch with previous implicit declaration warning: previous implicit declaration of 'Example()'类型2：显⽰：warning: unused variable 'param'。警告原因：很明显，是您定义了变量‘param'，却根本没有使⽤它。解决⽅法：不需要⽤的话，就删了它吧。类型3：显⽰：warning: statement ...
Global variable initialization is not supported. Therefore, you can not initialize a global such as int i = [expr]. Dereference is incomplete. Consider int x = 5; int *ptr = &x; and it is forbidden to use *ptr. However, it is valid to use ptr[0], which behaves the same of *ptr...
