definition

I tested on two compilers, and was surprised to see both support the following definition without complaint: class A { A(); }; A::A::A() {} ^^^ Note that this also succeeds for methods, although it is flagged when the declaration is over-qualified. Questions: Is this a valid C++ program? If so, what purpose does it serve - or is it merely a byproduct? Updated Detail: In case the original question was not clear or too short: I'm curious why redundant qualifications are permitted on the definition (emphasis also added above). Clang an Apple's GCC 4.2 + LLVM were the compilers Yes, it's allowed (

Recently I tried to Access a textbox from a thread (other than the UI thread) and an exception was thrown. It said something about the "code not being thread safe" and so I ended up writing a delegate (sample from MSDN helped) and calling it instead. But even so I didn't quite understand why all the extra code was necessary. Update: Will I run into any serious problems if I check Controls.CheckForIllegalCrossThread..blah =true Gregory Pakosz Eric Lippert has a nice blog post entitled What is this thing you call "thread safe"? about the definition of thread safety as found of Wikipedia. 3

What is Unit test, Integration Test, Smoke test, Regression Test and what are the differences between them? And Which tools can I use for each of them? For example I use JUnit and NUnit for Unit testing and Integration Testing. Are there any Smoke Test or Regression Test tools? ddaa Unit test : Specify and test one point of the contract of single method of a class. This should have a very narrow and well defined scope. Complex dependencies and interactions to the outside world are stubbed or mocked . Integration test : Test the correct inter-operation of multiple subsystems. There is whole

Let's say my web service is located at http://localhost:8080/foo/mywebservice and my WSDL is at http://localhost:8080/foo/mywebservice?wsdl . Is http://localhost:8080/foo/mywebservice an endpoint, i.e., is it the same as the URI of my web service or where the SOAP messages received and unmarshalled? Could you please explain to me what it is and what the purpose of it is? This is a shorter and hopefully clearer answer... Yes, the endpoint is the URL where your service can be accessed by a client application. The same web service can have multiple endpoints, for example in order to make it

This question already has an answer here: Alternative (K&R) C syntax for function declaration versus prototypes 5 answers I've seen a few function definitions like this recently while playing with GNU Bison: static VALUE ripper_pos(self) VALUE self; { //code here } Why is the type of self outside of the parenthesis? Is this valid C? sth Those are old K&R style function parameter declarations, declaring the types of the parameters separately: int func(a, b, c) int a; int b; int c; { return a + b + c; } This is the same as the more modern way to declare function parameters: int func(int a, int b
