In C++, to declare an object of a class that has a member variable as const, we must have a user-defined default constructor. The following code illustrates this. class Some { int value; }; int main() { // error: default initialization of an object of const type 'con...
The basic intent is that they usually mean the same thing. The big difference is that curly braces eliminate the "most vexing parse" where you tried to define an object, but end up actually declaring a function instead. So,NavEKF EKF{&ahrs, barometer, sonar};isusuallygoing to be equivalen...

The return value is a pointer to a function, which is also an address in memory. Both of these must be declared LongPtr in 64-bit VBA. The argument wMsg is used to pass data, so can be Long in both 32-bit and 64-bit.How to determine what is a memory address and what is data...
There are objects in Objective-C which are not NSObjects (the ones you'll meet in Cocoa at the moment are NSProxy, Protocol and Class). If some code expects an object of a particular class, declaring that helps the compiler check that you're using it properly. If you really can take...
