DSP algorithms, such as the example digital filters, usually require data in a range of addresses (a buffer) to be addressed so that the address pointer "wraps-around" from the end of the buffer back to the start of the buffer (bufferlength). This pointer movement is calledcircular bufferi...
our overall task will continue to get as much processing as it needs, but it will complete in a shorter period of time. On some systems, the execution of subtasks will be interleaved on a single processor; on others, they can run in parallel. Either way, we’ll see a performance boost...
Now we can see why the code crashes on x86-32: TheLogfunction interprets the stack like this: 42 capacity size ??? ??? inte\0?? const char*appl const char*pointer→"%z: %d" The first four characters of the string are misinterpreted as a pointer, resulting in an invalid pointer tha...
The trailing semicolon and the omitted parameter names in each makes them prototypes. It would be nice if you showed us the complete declaration since both of these are missing the return type.We need to see the actual function call in your .cpp source file, not your interpretation of what...
So what can we do? One approach is to force the conversion to happen in a context in which it is allowed. auto widget = std::make_shared<Widget>(static_cast<IWidgetCallback*>(this)); This pre-converts theWidgetContainer*to aIWidgetCallback*so thatmake_shareddoesn’t have to ...
The world is running on C-powered devices. We use these devices every day whether we realize it or not. C is the past, the present, and, as far as we can see, still the future for many areas of software.
MFC's conversion function is cool. It lets you pass a CString anywhere you could pass a pointer to a C string. It lets you write CString s = "whatever"; MyFunc(s); // MyFunc wants LPCTSTR whereas with STL, you have to explicitly invoke string::c_str. ...
In short. 1. Reference is just designed to support glorified "address passing", primarily used as parameters and/or return values. Not to replace pointers. 2. Because pointers can "rebind", so we don't need the same thing twice.
Ideally, we want it to be private. The only by-design way to get access to a private is to be inside the class. And now a full solution becomes very straightforward: using System; using System.Collections.Generic; public abstract class Item { public Item Parent ...
