I have a visual studio solution. I have many projects in the solution. There is one main project which acts as the start up and uses other projects. There is one project say “ProjectX”. Its reference is added to main project. The ProjectX references another .NET dll (say abc.dll) that isn’t part of the solution. … Read more
Why is it not allowed to get non-const reference to a temporary object, which function getx() returns? Clearly, this is prohibited by C++ Standard but I am interested in the purpose of such restriction, not a reference to the standard. struct X { X& ref() { return *this; } }; X getx() { return X();} … Read more
I was reading the lifetimes chapter of the Rust book, and I came across this example for a named/explicit lifetime: struct Foo<‘a> { x: &’a i32, } fn main() { let x; // -+ x goes into scope // | { // | let y = &5; // —+ y goes into scope let f … Read more
What would be better practice when giving a function the original variable to work with: unsigned long x = 4; void func1(unsigned long& val) { val = 5; } func1(x); or: void func2(unsigned long* val) { *val = 5; } func2(&x); IOW: Is there any reason to pick one over another? 12 Answers 12
I’m learning/experimenting with Rust, and in all the elegance that I find in this language, there is one peculiarity that baffles me and seems totally out of place. Rust automatically dereferences pointers when making method calls. I made some tests to determine the exact behaviour: struct X { val: i32 } impl std::ops::Deref for X … Read more

I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from … Read more
I have four projects in my Visual Studio solution (everyone targeting .NET 3.5) – for my problem only these two are important: MyBaseProject <- this class library references a third-party DLL file (elmah.dll) MyWebProject1 <- this web application project has a reference to MyBaseProject I added the elmah.dll reference to MyBaseProject in Visual studio 2008 … Read more
1) When an array is passed as an argument to a method or function, is it passed by reference, or by value? 2) When assigning an array to a variable, is the new variable a reference to the original array, or is it new copy? What about doing this: $a = array(1,2,3); $b = $a; … Read more
